Answer:

  (x, y) = (-2, -6)

Step-by-step explanation:

Equate the two expressions for y to get an equation in x alone.

  x -4 = 4x +2

  -6 = 3x . . . . . . . subtract 2+x

  -2 = x . . . . . . . . divide by 3

  y = -2-4 = -6 . . . use the first equation to find y

The solution is (x, y) = (-2, -6).
