#1 - (x-6)-(x+8)=9x How do I eliminate the parenthesis? Do I solve it by just removing the parenthesis, which leaves x-6-x+8=9x? From there I combine like terms, which makes me discover something: what is x+-x? Since x has a coefficient of 1, isn't it 0? But an unknown number and a negative unknown number isn't always 0, so :?: I have four answer choices: A)-7/2 B)-14/9 C)-7/3 D)-1/9 Any way I solve it I don't get any of these. :? Thanks for your help.

#2 - A similar problem to #1, but lengthier. -3(x+3)-(4x-6)=-9 I think what's confusing me in all of these are those parenthesis. I'm supposing I just remove them. Doing that, I get here: -3x

**+-**9-4x-6=-9 What do I do with those two +- signs? Or did I do something wrong?

I am feeling completely befuddled...please help me straighten this out. Thanks a LOT!
