Answer:

x = 2, y = -2

Step-by-step explanation:

Solve for y in terms of x in the top equation: 2x + 2y = 0

2y = -2x

y = - x

Now, substitute -x for y in the second equation and solve for x:

-3x -2(-x) = -2

-3x + 2x = -2

-x = -2, so x = 2

Now substitute x = 2 into the first equation and solve for y:

2x + 2y = 0

2(2) +2y = 0

4 + 2y = 0

2y = -4

y =  -2
