Question

Solve the system by substitution.

Answer 1

So do you know what substitution means?

Answer 2

@retirEEdWell I assumed that substitution wold be moving 6y to the the other side so it'd be x=6y+2 and then simply plugging it in to 5x+4y=36 like 5(6y+2)+4y=36 but I couldn't get the correct answer by doing this. Btw I do have the correct answer (In the answer key) but I'd like to know how to answer question like this.

Answer 3

Your steps are correct. Just do it again in here and I can tell you if you do anything wrong.

Answer 4

5(6y+2)+4y=36
Solve for y.

Answer 5

Do you need help on where to get started to solve for y Zuha?

Answer 6

Alright
-30y+10+4y=36
-26y=26
y=-1

Answer 7

Ah I think I was doing 5(6y+2)+4y=36 instead of 5(-6y+2)+4y=36

Answer 8

Probably.
Your work is right. Just plug back in for y and solve for x.

Answer 9

Alright, thank you both very much!
