Question

Solve Each System Using Substitution.
y-2x=3
3x-2y=5

Answer 1

Solve for y in the first equation and plug it into the second equation

Answer 2

but how do i get y=
for the first equation givin

Answer 3

rearrange the equation to get y= ...

Answer 4

what are the steps to rearrange it

Answer 5

For the first equation, just plus 2x to both sides to get:
y-2x+2x=3+2x
The 2x's on the left hand side cancel out as (-2x)+2x=0
Therefore you get
y=3+2x.

Answer 6

Then you just replace the y's in the second equation with 3+2x ...since y=3+2x.
And solve.
