- 👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by substitution, we solve for one of the variables in one of the equations and then substitute for the variable in the other equation and then solve for the other variable. Next we plug in the obtained value of the other variable into the equation for the initial variable we solved for to obtain the value of the variable.
The value of the two variables obtained is the solution to the system of equations.

Thanks so much, my teacher lacks in the teaching part and gives homework, now I understand it and can actually do it
SAME DUDE
Frr
This man saved me from failing so many tests 😭
Currently studying for a test 😂
@@Ally.Dance. me too
Me too 😅
Same here
coming right back at ya lol
The one dislike is elimination
i just grew a braincell watching this
What happens if I don't have a variable that has a variable of 1 or -1?
What if both equations are already isolated and are X how do I substitute them?
I noticed you use the word true instead of equals, which is good, because I think students need to know the value of symbolic logic. That something is either true or false. This is particularly important when you're talking about inequalities.
Bro literally better than my math teacher
I want to be in is class
you help so much
Man that went wayyy too fast when actually solving it 💀😭
Mr Brian mclogan how did you get the -10y?? Am confused about that part
-12y + 2y
Bro just unlocks to me other dimensions in my maths test thanks❤😊😊,and 2024 mary Christmas
me: finally i found this video been looking for this for weeks.
computer: crashes :/
Mr mclogan you have saved me from failing my math class my teacher is ms spencer if you remember her. She said she met you.
Omg Ms Spencer??? Tell her I said hi my name is Alex btw
I have exam tomorrow, wish me luck!
1 year later how was the exam cuh
Fr
My math teacher isn't very good at actually teaching so this is SO helpful!! I'm now going to pass my exams!!!
did u pass?
Thanks so much!
Thank you so much for this video. This helped me & my 8th grader SOOO MUCH!! Thank you!!
You teach so well! Thank you for your help :D
shi dont make sense
I❤you my best math solver teacher
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Please keep it up like the best one, Ike you're the only one in the whole world ❤❤❤❤❤❤
Thx
Shout out to Bryan for carrying my grades fr
My bad i meant Brian🙏
Where did get the 1 from (X=1-4y)??
Thankyou for helping me I wouldn't have passed my exam without your teaching 😊😊
Thanks so much bro just saved my life
Hey that really helped me for my homework
This man should be the owner of kumon
What grade you teaching
why did you subtract 3 on both sides?
Everything you do on one side you do the same on the other side
Thank you so much ily
Nice
Thank you. Where I was learning this was about to make my head explode because the explanation was horrible but you just helped me
thank you
Wow u saved me. Good explaining on substitution method!!
Thank you thank you thank youuuuu! I did some exercises to see if I understood, i got them all right, and now I’m ready for my exam!!!
Merry crisis
where did the subtraction icon come from
Thank you 💛
देव तुमचं भल करो.
I love you
But sir, what if there are no variables with coefficients of 1 or -1? And have to use substitution?
there are 2 other methods, graphically and elimination, let me know if this helped!
Bro how can I solve
(X+2y=4
(2x-y=3 😭
I love you
Thank you THATS all I have to say hazzzzzzzzza
what happened to your head?
Holy shit, I'm gonna lose that exam tomorrow
Did you fail😭
@@toefungus4575 I actually passed, barely tho
I got an exam next week, this is make it or break it for me
@@HBIsBlessed you can make it bro, I did it and you can too.
I also have an exam tomorrow actually, this time about logarithms and exponentials and other shit but I have trust in you and in myself
ty
mwah
Hello
Im here, watching this man cuz im trying to get into AI and i need to understand some algebra to do it
This explanation made it so much easier, I will NOT crash out now. Thank you☺️🫶
