Answer:
(x, y) = (12, -12)
Step-by-step explanation:
The two equations can be added to solve for x.
(-5x -5y) +(6x +5y) = (0) +(12)
x = 12 . . . . . . . . simplify
-5(12) -5(y) = 0 . . . substitute into the first equation
12 +y = 0 . . . . . . . divide by -5
y = -12 . . . . . . . . subtract 12
The solution is (x, y) = (12, -12).
