You can simplify this expression by combining like terms. You can see that you can subtract 3x from 21x leaving us with (your answer): 18x + 9. You could also factor this to look like 9(2x + 1). Whichever one you prefer :))

8x-6y=-96 add to this -4 times the second equation...
-8x-12y=-48
___________

-18y=-144

y=8, this makes 8x-6y=-96 become:

8x-48=-96

8x=-48

x=-6

so the solution to the system of equations is the point:

(-6,8)
