Use substitution to solve each system 2y-2=4x y=-x+4

x = 3

y = 7

Step-by-step explanation:

First we need to substitute the equation from

2y-2=4x to...

2x + 8 - 2 = 4x.

Now we simplify.

8 - 2 = 6. 4x - 2x = 2

Now we have to find x alone. so .

Now we need to find y. So we factor in the x.

y = 3 + 4

y = 7.

So

x = 3 and

y = 7

2
