Answer:

  (x, y) = (-112, -264)

Step-by-step explanation:

Start by clearing fractions. Multiply the first equation by 4 and the second one by 8.

  2x -y = 40

  x - y = 152

Subtract the second equation from the first.

  (2x -y) -(x -y) = (40) -(152)

  x = -112

Using the second equation, we can find y:

  y = x - 152 = -112 -152

  y = -264

The solution is (x, y) = (-112, -264).
