Answer:

(2,-3)

Step-by-step explanation:

2x + 2y = -2

3x -2y =12

Add the two equations together to eliminate y

2x + 2y = -2

3x -2y =12

--------------------

5x = 10

Divide each side by 5

5x/5 = 10/5

x =2

Now we need to find y

2x+2y=-2

2(2) +2y = -2

4+2y = -2

Subtract 4 from each side

4-4 +2y = -2-4

2y = -6

Divide each side by 2

2y/2 = -6/2

y =-3
