A. (-3,0)
Add the two equations together so one variable is eliminated:
5x + 2y = -15
+ 2x - 2y = -6
-------------------------
7x = -21
7x = -21
Solve for x:
x = -21 ÷ 7
x = -3
Now substitute x to any of the equation to solve for y. (I'll choose the second equation):
2x - 2y = -6
2(-3) - 2y = -6
-6 - 2y = -6
-2y = -6 + 6
-2y = 0
y = 0
x = -3
y = 0
