Question

Solve for x and y

need help fast.

Answer 1

X equals 4, Y equals negative 8

Answer 2

(x, y) = (4, -8)

Explanation:

2x - 2y = 24
`$\Rightarrow$` 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
`$\Rightarrow$` 2x = 8
`$\Rightarrow$`x = 4
