I'm confused. How did you get the -12x?

I knew it. I knew that whoever answered this actually answered in binary. Good job. Have a thumbs-up.

Darn, I knew I should have considered fractions. Thanks, CPhill.

Huh. Alrighty then. Thanks very much, guys.

Well, if you wouldn't mind helping w/ one of those two-sided ones, that'd be great. Is it done the same way, just using the formula on both sides?

Well, to be fair, that isn't all of it.

But I seriously thought the point of this site was to get help with math homework. Granted, I could (and should) have just asked for you guys to answer one and then applied the steps to the rest.
