−5x+9y= −32

−5x−3y= 4

Find solution of the system of equations.

  (x, y) = (1, -3)

Step-by-step explanation:

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

  (-5x +9y) -(-5x -3y) = (-32) -(4)

  12y = -36 . . . . simplify

  y = -3 . . . . . . . divide by 12

Substituting into the second equation, we have ...

  -5x -3(-3) = 4

  -5x +9 = 4 . . . . . simplify

  -5x = -5 . . . . . . . subtract 9

  x = 1 . . . . . . . . . . divide by -5

The solution to the equations is (x, y) = (1, -3).
