Answer:

1. y=3

2. y=3

Step-by-step explanation:

Let's start with the first one, 2x-2y=-8...

  • Substitute x with -1 -----> 2(-1)-2y=-8
  • 2 times -1 makes -2 so new equation is ---> -2-2y=-8
  • Now add 2 on each side to get rid of 2 and get this ----> -2y=-6
  • Now divide -6 by -2 to get this ---->  y=3

Let's start with the second one, 2x+2y=4

  • Substitute x with -1 -----> 2(-1)+2y=4
  • 2 times -1 makes -2 so new equation is ---> -2+2y=4
  • Now add 2 on each side to get rid of 2 and get this ----> 2y=6
  • Now divide 6 by 2 to get this ---->  y=3

I hope my explanation and answer helps:)
