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
