Answer:
(x, y) = (-112, -264)
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).
