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).
