Answer:
(x, y) = (4, -8)
Step-by-step explanation:
2x - 2y = 24 [tex]$\Rightarrow$[/tex] 4x - 4y = 48
4x + 7y = -40
Subtracting the two equations from each other, we get:
(4x + 7y) - (4x - 4y) = -40 - 48
11y = -88
y = -8.
Then, 2x - 2*(-8) = 24. So, 2x + 16 = 24 [tex]$\Rightarrow$[/tex] 2x = 8[tex]$\Rightarrow$[/tex]x = 4
