Get all the terms that have x in them on one side and
all the terms that don't have x in them on the other side:



Factor out x, the letter you are solving for:



Divide both sides by 







But you aren't finished yet because you can
factor a out of the denominator on the right:



Then cancel:



  

Be sure you realize that you don't get 
 because the  was in a denominator and
you must keep it in the denominator after canceling
out the 's by putting a 1 over it.
