Solve the following system of equations

  (x, y) = (-2, -5)

Step-by-step explanation:

Given that x=-2, you can use either equation to find y.

  9(-2) -8y = 22

  -8y = 40 . . . . . . add 18

  y = -5 . . . . . . . . .divide by -8

Check in the other equation:

  -8(-2) +5(-5) = -9

  16 -25 = -9 . . . . . . true, so (x, y) = (-2, -5) is the solution.

y = -5
