Question 121951: I'm actually not sure if this question falls in this category but it looks like it does. I help my daughter with her Math homework every night but for some reason, this question really has me stumped. Please help!
-3(x+4)=3(3-x) what does x equal??? I've tried -3x-12=9-3x then i added 12 to each side: -3x=21-3x i then tried to add 3x to each side but that didn't seem to work. the best answer i could come up with was x-x=7 and that just doesn't make sense.
thanks!!

-3(x+4)=3(3-x) what does x equal?
-3x-12 = 9-3x
-12 = 9
That is a contradiction and tells you
there are no solutions to the equation.
================
Why did that happen?
It happened because you assumed the "x" on
the left side had the same value as the "x"
on the right side.
As a result you ran into a contradiction.
x on the left cannot equal the x on the right.
==============================

There is nothing wrong with what you have done here!
The answer is that the "equation" you have is inconsistent and there no value of x that will satisfy it so no matter what value of x you choose, the left side will never equal the right side.
