- Solving multi-step equations is a fundamental algebra skill. When learning about linear equations you first start with 1 step equations, then 2 step equations and finally multi-step equations. For more math help please visit tabletclass.com
Who else watched this video before their math test?
I am lol
Dorothy Wells lol
Dottie Annie yup warren Mott sufdkscfagahahwjs
Me too mate
almighty shrek Mott?
A 10 minute video is better then Several hours in class isn't that something
pastel/dark dimond agreed
True
I can agree
A 10 minute video with 10 ads
Dude ik he's the best
thank you so much ... right now im trying to figure out why is it that a teacher in actual school takes forever to teach something so simple and makes it 1000448735972x harder but tablet class just gave me perfect understanding in 2 minutes !!!!!!!!!!
The videos 10 ma'am.
Jayden Lin ya but she understands it in 2 mins cuz she is a teenager/child
I wish he was my teacher in school
Omg thank you so much I tought I am stupid cause it was to confusing when our instructor show us i was about the drop my math class God bless you ❤
@@Shadowomission 👍🤷♀️
How could a 10 minute vid be better then 1 hour of a math period
This is a rare time where the teacher explained it without saying anything
Thanks! I was lacking on my math and my average score went lower, now that youve helped me, i understand how it works now. Thx!😊
So I missed one class and I did not want to hold the class back so this guy he’ll me a lot
thanjs man I understand it more and thanks for walking me through instead of saying try it
I still don’t get it 🙄
You distribute when you see parentheses, before you look for things with the same symbol and combine them, before you solve the damn problem.
*SIMPLE, RIGHT*
Jayden Lin well thank u even tho I still pass my math class 😂
Thank you so much you saved me from getting behind in online school thank you so much you rock! (Ps: I wish you were my math teacher your so much simpler, you can explain things in 10 minutes while teachers be taking 2 class periods to explain 1 step equations, Godspeed mah dude!)
I am watching this video becuase I am in quarantine and I left all my notes in my locker. I have this math packet that was mailed to me and it's due really soon and I forgot how to do multi step equations 😂💀
Tae👀
Edit: okay this is future me looking at my past comment: Wth how do your forget to do multi step equations? Oml they are literally the easiest thing to do in the world. Omg past me, you were stupid af.🤦♀️🤦♀️🤦♀️
@@jaenmiyuki6357 it's a good thing you think it's easy I still have a math quiz to do

That is what google is for my friend
Clearly explained. Thanks
My math teacher almost never teaches us, so thanks for the help. Much appreciated
I'm 51 years old and even though it's been years since high school and college math I am getting them correct, but in my personal and professional life I have never needed to use algebra. Thankfully

@REBECCA ROBERSON yay!
Best math teacher
I sort of finally understand multi step equations now!
Yeah I’m back in college. And my first set of classes of College algebra.. this channel is about to be my bestie for the semester 😂
I can't find any rules for this.... what side of the equal sign do I cancel out... is the rules for bigger numbers ... ex
Fantastic! I'm redoing math Billy Madison style and you are helping a lot.
Thanks from a Mom helping her teen ;)
THANK YOU! it’s been very difficult for me but this really helped
thx i had a math test today and didnt finish because i didnt understand but now i do so thx i will pass the test
you helped me so much. thank you!
My math test is literally on Tuesday this was such a life saver! Omg ❤
Very helpful! Thank you!
Bro this was the biggest life saver
Thx
Thank you so much!! I’ve missed two weeks off my 2nd trimester this 8th grade year and I had no idea how to solve these but you seriously help me out so much, I wish you the best in life!. Looking forward to learn more from you!

Thanks for the help bro
thank you so much
On one of the problems I got positive 22 instead of negative 22 is it still considered right?
Idk my brain is too small and smooth to answer your question
thank u
Could you please make a video on factoring special polynomials?
I'll go ahead and start banging head against the wall to keep myself from asking what that is.
@@jaydenlin3780 LOL mmmhm, all I know is that it gets a lot fucking harder. Grade 10 to 12 is a big jump ✌️
You saved my life
Thank you
Hello. On the last problem isn’t it 22 instead of -22 ? Because on 22/-1the biggest number is positive. Thanks so much
No, it'd be a positive number if both dividend and the divisor were negatives, but since only one is negative, the quotient must be negative.
Bro this just saved my life ngl
Can you explain pls
@@alisonrosales3319 of course 2 months ago a had a benchmark which in my school is kinda like how stupid are you my dumbass self forgot you to do this so yeah it saved my life
Thank u sir
He did not solve the last problem with “y” on both side. Instructions were pause and work the problem. The last problem on the first page was not solved
I hate school. The moment I get something down pat, it blasts more and harder crap in my face. Just, why?
U can do it believe me
I feel the same try a good cry u can do it :)
5:07 how did it go from 3 to 4
Oml i literally have a test tmr and im in advanced math the teacher cant teach math correctly if his life depened on it i cant do this anymore 😂😢
How is it 20 if u said “subtracting 6 from both side”
14 is a negative and 6 is a positive and if you subtract -14 from 6 you are going to get -20
GSTH Zombie this is what math teachers never say unless you ask
negative plus a positive or vise versa equals a negative
It's -20. -14+(-6) or -14-6 is -20.
Like, BOI.
@@matthewlake4862 also, don't listen to this Matthew dude, a negative 6 plus a positive 8 does not equal a negative.
You never gave the answer to the third problem in the first set of equations
Who else watching this right before math class lmao
sir what is 1-2 plz i ned help. I got F test
- l your welcome
I am so confused on when he says subtract 6 from both sides but he adds -14+-6=-20 isn't-14--6=-8??😢

Why is this stuff so hard? Why am i not learning? Im almost 40, had knowbody help me while i was young. This is crazy stuff. Im looking 6th grade Algebra and still cant fig it out....i feel like my 5th grade son is smarter than me....and he is....are you smarter than a 5th grader? Noooooppppeee!!!!
Coming from an 8th grader in Algebra 1, I learned this in 6th grade, forgot over the summer, then learned again in 7th grade. You forget things if you don't use them. For example, what good is 3(y+2)+y = -14 when you work at a job that doesn't use it. If you didn't learn when you were young that's the problem, when your young and want good grades you constantly use this math so you remember it.
For me, all of my teachers don't teach the way that would be best for me. They explain stuff in ways that I don't understand. What I've found out is that you need a method of learning. I learn best visually. But I learn the process by doing. In other words, practice. I don't know how far you are at understanding, but I really hope this helps because while it may have not been as intense as your experience, I know what it's like to struggle learning new concepts, and sometimes it just needs to be re-explained in different words until it clicks.
3x + 3 = 24
You want the equation to look like x = a constant number. We are trying to find the value of x. So what does x multiply by, that you can add 3, to equal 24. We can do this by reversing the equation, let me show you.
It's 3x + 3 = 24. Instead of 3x + 3 = 24, let's reverse the + 3, so we subtract 3. So we had 3x + 3, we want to take away the 3, so just subtract it, we are left with 3x. But, what we do to one side of the equation, we have to do to the other to make sure it's balanced. So,
3x + 3 = 24
- 3 - 3
3x = 21
Do you see how we did that? We want to isolate the variable. So the variable is equal to a constant. If we subtract 3 from the left side, we must subtract 3 from the right side to create balance.
3x = 21
So 3 times some number, (x) is = to 21.
x = 7.
This is because 3 * 7 = 21.
To get more technical, do you remember how I said we have to balance both sides of the equation? So if we minus 3 on one side, we minus 3 on the other side too. This also applies to addition, multiplication, and division.
So using math,
3x = 21
__ __
3 3
We divided 3x by 3, so to keep it balanced we also have to divide 21 by 3.
3x into 3 different parts is just 1x, or x. ( 3x/3 )
21 into 3 different parts is 7. ( 21/3 )
x = 7.
__________________________________
So what if we have,
x - 2 = 9
So we need to isolate the variable using reverse operations. So,
x - 2 = 9
+ 2 + 2
The opposite of subtraction is addition. So in,
x - 2 = 9
We add 2, to both sides of the equation, -2 + 2 is 0, so we are left with just x,
and 9 + 2 = 11
So x = 11
We got the variable by itself, and we got it to equal a constant number.
__________________________________
What if we have, x + 2 - 4 + 8 - 1 = 40? It might look intimidating at first but its simple.
We have two sides of the equation,
x + 2 - 4 + 8 - 1 and 40
On the left side, you notice we have a bunch of numbers, these numbers are alike-terms. So we must need to do,
x + 2 - 4 + 8 - 1, just like a regular math problem, but a + x at the end, or beginning.
2 - 4 + 8 - 1 = 5
But we also had an x at the beginning, so it's simply 5 + x, or x + 5.
On the right side of the equation we had 40, so,
x + 5 = 40
- 5 -5
x = 35
Do you see how it works. We just break the process down and learn each thing one at a time.
How about,
3(x+8) - 2 = 7
We need to use what we call the distributive property of multiplication. This means that when we have a number before a set of parenthesis, we just multiply it by everything in the parenthesis. So,
3(x+8) is,
3*x + 3*8
3x + 24
3 times x, is just 3x. 3 times 8, is 24. Then we drop the parenthesis.
So 3x + 24 is what we have, but we also have the rest of the equation, which is now,
We just put 3x + 24 in 3(x + 8) spot in the equation because they are equal.
3x + 24 - 2 = 7
Remember what we did when we have alike-terms?
24 and - 2 are alike terms on the left side. So, 24 - 2 = 22.
So, 3x + 22, and with the rest of the equation it becomes,
3x + 22 = 7
Notice how this problem now looks like our first one. We just isolate the variable, now.
3x + 22 = 7
- 22 -22
3x = -15
So we just divide 3x by 3, which is x.
x =
Then we divide -15 by 3, which is -5
x = -5
We can even check our answer if we weren't sure.
Our equation was 3(x+8) - 2 = 7
We can plugin -5 for x and get.
3(-5+8) - 2 = 7
Inside the parenthesis we have like terms, so we combine them and get,
3(3) - 2 = 7
So we distribute the 3 to whats inside the parenthesis, and get 9, because 3*3=9
So 9 - 2 = 7.
7 = 7.
If they were equal, then our answer is correct.
__________________________________
Remember our alike-terms? -7, 5, 2, 9. There can also be alike-terms for things that have variables.
3x, 4x, -2x, 9x. These are also alike-terms, keep that in mind.
So if we have an equation like 4(x + 2) + 3 - 2x = 15
First we distribute the 4 into everything inside the parenthesis. So, 4x + 8.
We replace it, so,
4x + 8 + 3 - 2x = 15.
We have two sets of alike-terms. We need to combine them.
4x and -2x. This is just 4x - 2x, so 2x.
8 and 3. This is just 8 + 3, so 11.
2x + 11 = 15
And, again, look how we simplified it and it looks like our beginning equation, you should know what we do from here (;
2x + 11 = 15
- 11 - 11
2x = 4
__ __
2 2
x = 2.
We can also check our answer, we just find every term that has x, and replace it with a 2.
So if x = 2, and the equation is 4(x + 2) + 3 - 2x = 15
If we substituted every x for 2, it would look like.
4(2 + 2) + 3 - 4 = 15
16 + 3 - 4 = 15
19 - 4 = 15
15 = 15
So our answer is correct.

He didn't get 20, he got negative twenty. The fourteen is negative and when you subtract six from negative fourteen, you get negative twenty. If you are hear doing here learning multi-step equations and don't know how negative, consult a math teacher or a parent.
