Answer:

  (x, y) = (40, 11/3)

Step-by-step explanation:

The variable x can be eliminated by subtracting the first equation from the second.

  (x -9y) -(x -12y) = (7) -(-4)

  3y = 11 . . . . . . .simpify

  y = 11/3 . . . . . .divide by 3

  x -9(11/3) = 7 . . . . substitute for y in the second equation

  x = 40 . . . . . . . add 33

The solution is (x, y) = (40, 11/3).
