x - 4x = 12 can be rewritten as -4x + 1x = 12
Therefore -3x = 12
Divide both sides by -3 and you end up with x = -4

considering how easy algebra at this level is...
not being able to do this is no different than being incapable of
4+4
Algebra at college levels: a different story..
Thanks for the points anyway... though a person must be an idiot if you cant solve for this.

x = -4
-4 - -16 converts to
-4 +16 which = 12
So x is negative 4

no, it's -4.
when you see just x in there, it means 1x. so 1x-4x= -3x.
-3x=12 x= -4
The people answering these questions are unbelievably bad, I'm sorry.

Please learn to do the home work yourself. Otherwise you will never know how to do it. Read the examples in the book and do it.
Also learn to remember the mulitiplication table. It will help you big time.
OK?!

Do your own homework....otherwise its cheating. You'll learn more if you don't ask other people to do your own homework.
