Question

-4x -2y = -12
4x + 8y = -24

Answer 1

x= 6 and y= -6

Explanation:

Answer 2

x = 6, y = -6

Explanation:

After adding the equations together, the 4x and -4x cancel each other out. This makes our new equation:

6y = -36

Divide both sides by 6

y = -6

Plug -6 into y in one of the equations

4x + 8y = -24 =

4x + 8(-6) = -24 =

4x - 48 = -24

Add 48 to both sides

4x = 24

Divide both sides by 4

x = 6
