Question

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

Answer 1

Hello!

First you have to find either x or y

We can use the second equation to find y

-8 + 2y = -20

Add 8 to both sides

2y = -12

Divide both sides by 2

y = -6

We can plug -6 in for y in the other equation

-8x - 8(-6) = 0

-8 * -6 = 48

-8x + 48 = 0

subtract 48 from both sides

-8x = -48

divide both sides by -8

x = 8

So the answers are x = 8 and y = -6

Hope this helps!
