SOLUTION

Finding for the value of k

  • (x+4) = k/(y-3)

Substitute x = 8 , y = -2

  • (8+4) = k/-2
  • 12 = k/-2
  • 12(-2) = k
  • -24 = k

Finding for the value of x

  • (x+4) = -24/(y-3)

Substitute y = 1

  • x+4 = -24/(1-(-3))
  • x+4 = -24/1+3
  • x+4 = -24/4
  • x+4 = -6
  • x = -6-4
  • x = -10

ANSWER

  • x = -10
