1. x = 0, y = 4

2. x = -3, y = -5

Step-by-step explanation:

1. Substitute x by 4 - y

Now you have 2y + 4 = 12

Solve for y and you have y = 4

Substitute y and you have x = 0.

2. Substitute y by x - 2

Then you get 2x - 3(x-2) = 9 [Note: Distribute the negative sign]

After distributing you get -x + 6 = 9

Solve for x and you get x = -3 (Multiply -1 on both sides)

Substitute x now and y = -5

Hope this helps.
