Question

Can someone please help me? I'm horrible at math !

2x + y = 11
3y - 4y = 11

you have to solve the problem using substitution.

please help.

Answer 1

3y - 4y= -y

Answer 2

canu tell me wat is -4y+3y

Answer 3

yes thank you

Answer 4

Solve 2x + y = 11 for y.
y = 11 - 2 x
Replace each y in the second equation with 11 - 2 x and solve the result for x.
Can you take it from here ?

Answer 5

it would be 33/7

Answer 6

y = 11-2x

3y - 4y = 11
3•(11-2x) -4•(11-2x) = 11
Does that help?

Answer 7

33 -6x -44 +8x = 11
-11 + 2x = 11
2x = 22
x = 11

y=-11
