Question

Solve the following system by any method. -8x-8y=0 and -8x+2y=-20

Answer 1

Answer:

$x=2\\y=-2$

Step-by-step explanation:

$-8x-8y=0$

Solve -8x-8y=0 for x

$-8x-8y+8y=0+8y$

$-8x=8y$

$x=-1y$

$-8x+2y=-20$

Substitute -1y for x

$-8(-1y)+2y=-20$

$8y+2y=-20$

$10y=-20$

$y=-2$

Substitute -2 for y

$x=-1y$

$x=-1(-2)$

$x=2$

Answer 2

X=2

y=-2
