Find the solution of this system of equations. Separate the x - and y-values with a comma.

x = - 12 + y

-6x + 2y = 28

The answer is Y=11, X=-1

Here's my work:

x=-12+y

-6 (-12+y) + 2y=28

6*12 = 72

72 - 6y + 2y=28 (now we combine like-terms)

72-4y=28 (now divide by - 4)

-18+y=-7 (add 18 to both sides)

y=11

next part we find x:

x=-12 + (11)

x=-1
