Answer:

x = -4

y = -2

Explanation:

All you need to do is plug in the number given for y into the equation:

-4x + 8y = 0

-4x + 8(-2) = 0

-4x - 16 = 0

Add 16 to both sides:

-4x - 16 = 0

+ 16 + 16

____________

-4x = 16

Finally, divide both sides by -4:

-4x = 16

x = -4

So now you have, x = -4 and y = -2
