Question

Solve for x, y, and z. Show all your work.

−6x − 2y + 2z = −8
3x − 2y − 4z = 8
6x − 2y − 6z = −18

Answer 1

1. X= - -4+y-z/3

Explanation:

1. -6x-2y+2z=-8

1. Subtract -2y+2z from both sides -6x-2y+2z-(-2y+2z)=-8-(-2y+2z)

1. Simplify -6x=-8+2y-2z

1. Divide both sides by -6 -6x/-6 = - 8/-6+ 2y/-6 - 2y/-6
