$x = 2$ $x=2$
$y = - 2$ $y=-2$

Explanation:

Given -

$- 2 x - 2 y = 0$ $-2x-2y=0$ ---------------------------(1)
$- x + y = - 4$ $-x+y=-4$ ----------------------------(2)

$- x + y = - 4$ $-x+y=-4$ ----------------------------(2) $\times 2$ $xx 2$

$- 2 x + 2 y = - 8$ $-2x+2y=-8$ -------------------------(3)
$- 2 x - 2 y = 0$ $-2x-2y=0$ ---------------------------(1) $3 + 1$ $3 + 1$
$- 4 x = - 8$ $-4x=-8$
$x = \frac{- 8}{- 4} = 2$ $x=(-8)/(-4)=2$
$x = 2$ $x=2$

Substitute $x = 2$ $x=2$ in equation (2)

$- (2) + y = - 4$ $-(2)+y=-4$ ----------------------------(2)
$- 2 + y = - 4$ $-2+y=-4$
$y = - 4 + 2 = - 2$ $y=-4+2=-2$
$y = - 2$ $y=-2$
