Answer: (2, 5)

Explanation:

2x-2y= -6

First divide both sides to yield:

x-y = -3

Then multiply both sides by -3 to yield:

-3x + 3y = 9

5x-3y = -5

If we add these 2 equations together, we will eliminate the y's:

2x + 0y = 4

2x = 4

x = 2

Plug 2 back into x - y = -3

2 - y = -3

Subtract 2 from both sides

-y = -5

Multiply both sides by -1

y = 5
