Answer:
x = 4; y = -8
Explanation:
0.5x + 0.5y = -2
x - 0.25y = 6
Rewrite the first equation. Multiply both sides of the second equation by 2 and write below the first equation. then add the equations.
0.5x + 0.5y = -2
+ 2x - 0.5y = 12
---------------------------
2.5x = 10
x = 4
x - 0.25y = 6
4 - 0.25y = 6
-0.25y = 2
y = -2/0.25
y = -8
x = 4; y = -8
