Answer from: meiyrarodriguez

(2,-3)

Step-by-step explanation:

2x+2y=-2

3x-2y=12

Add these two equations together to eliminate y

2x+2y=-2

3x-2y=12

5x = 10

Divide 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 by 2

2y/2 = -6/2

y = -3

Answer from: Franklyn3834

Step-by-step explanation:

You have two equations and two "unknowns" x and y.

This is an easy one. Add the two equations together, which will eliminate the y terms so you can solve for x:

2x+2y = -2

3x-2y = 12

5x  = 10,   so x = 2.

Now plug the 2 back into one of the equations and solve it for y.

2(2)+2y = -2

4+2y = -2

2y = -6

y = -3
