Get all the x terms to one side. Divide both sides by the number in front of the x term.
Hint: Get the x's on the left side.

OpenStudy (ipwnbunnies):
No, you can do this. What do you get when you move all the x's to the left side.

2?
OpenStudy (ipwnbunnies):
6x-8x = 8x + 10 -8x. We're trying to eliminate the 8x on the right side, so we have to subtract both sides by 8x.
OpenStudy (ipwnbunnies):
It'll be -2x, because 6x - 8x = -2, right?
OpenStudy (ipwnbunnies):
-2x*

that was wrong
OpenStudy (ipwnbunnies):
Good, so -2x = 10. Nothing happened to the 10 yet b/c we were only working with the x terms.
OpenStudy (ipwnbunnies):
Well, we didn't solve for x yet.
OpenStudy (anonymous):
oh im stupid
OpenStudy (ipwnbunnies):
-2x = 10; how can we get x by itself now?
