That's a part of the two step equation. this is how you solve bigger numbers that you can't do in your head. the opposite of +5, is --5. those numbers cancel out each other. but 9-5 will get your answer.
@Jo.Bedwars so like above if the number is - 2 I need to +2 and place another +2 below another number? It's like a rule and it needs to be in the opposite like you mentioned? Sorry at my age 39 years old, I realised the fun in solving maths.. 😢 Thanks for replying you're doing great job for explaining and helping out bro
Because when you divide 8x by 8 you do 8÷8=1 and it turns into 1x and 1x is x itself so another way of saying it is x and you divide the other side by 8 so you can equal the sequence up.
2(4x +1) = 9 or 2(4x +1) = 9
8x + 2 = 9 4x + 1 = 9/2
8x = 9 - 2 4x = 9/2 - 1
8x = 7 4x = 7/2
x = 7/8 x = 7/8
I used method 2
😵💫🫨🥴😂
The one on the right looks hard
2(4x + 1) = 9
4x + 1 = 45/10
40x + 10 = 45
40x = 35
8x = 7
x = 7/8
4x+1=9/2
4x = 4.5 -1
x= 7/8
Faster way lol nice
Extra credit for clear, concise proof!
Good. No inexplicable shortcuts.
8x+2=9
8x=7
x=7/8
2 (4×1=4×1=4+1=5+2=7. 2×4=8+1=9-2=7
correct
How does 8x+ 2 equal 9?
Because in the end we know x= 7/8
@@mianhussain2357okay you're right hey I'm new to algebra
@@ralphmelvin1046 I’m also not that good at maths, but i like watching random math videos
@@mianhussain2357 oh I'm very good and basic math but algebra has me a little stooped
Question please..
Why we need to - 2 below +2 & 9?
Thanks

Thank youuuuu
THANK YOU😊
Why did you divide in the last step?
Because when you divide 8x by 8 you do 8÷8=1 and it turns into 1x and 1x is x itself so another way of saying it is x and you divide the other side by 8 so you can equal the sequence up.
Thanks Watches, got it!
Then how did u -2 -2 in the middle part of the equation?
How do u get it
(2 (4x + 1) = 9 )= 4x + 1 = 4.5
(4x + 1 = 4.5 )= 4x = 3.5
3.5 = x times 4 (x= (3.5 * 4) )
3.5 * 4 = 0.875. X= 0.875
7/8=0.875
0.875x4=3.5
3.5+1=4.5
4.5x2=9
The comments indicates they know more maths than you do, okay
x=7/8
8+2 is 10
Where do you even get the +2 underneath + 1? am confuzzle.
You multiply both numbers inside the parentheses by 2.
Right
Tysm
2(4x+1)=9
8x+2 = 9
I got lost here. How do we get
8x+2 = 9
When 2(4x+1) = 9
It's been a long time but, I think it's called the distributive property (I get the names confused) where A(B+C) = AB + AC
You have to divide 7/8 to get x=0.875
It would be better if you did the algebraic x
Yeah true.
1:40
8x=9-2...8x=7...x=7/8
x=0.875
Bro what about the exponent
Old goat here....I watched this several times and still don't understand what the hell he's doing.
A ojo, x=7/8
Why is nobody explaining you’re just doing it? You’re not explaining how you’re getting there
Yea
He’s not helping bro I don’t understand a thing
Il valore dell'equazione è 8x = 7 , x = 7/8
)( me trying to do the X in maths in brackets 😂
Can I just ask what is this questions mark out of this is just to compare both mine and yours 😅
I’m completely lost., how does 8x+2=9?
Same I dont get it shouldn't the answer be 10 idk I need help I completely dont get this but ty for the video
x = 7/8, mentally done let's GOO
🎉🎉🎉❤❤
Tf the 2 come from tho 😩🤣
Multiply 2 and 1
My teacher cant teach good so i need
I'm lost
I know these answers had two answrrs😊
I’m here because I searched bo6 terminus Easter eggs
What
bro i thought 8 + 2 is 9
I knew that already. Silly
Good. you can always swipe
1 1/8
4x+1=9/2
4x = 4.5 -1
x= 7/8
8x+2=9
-2
8x=7
X=7/8
x = 7/8
X=7/8
