Re: simplify......Help
At the very start all I did was add 1 and 4/u to get (u + 4)/u. The steps are all simple if you do them one at a time.

Re: simplify......Help
No , you use the C in your question , then you ignore it in the firest step of solution ,
you should end up with :
( CB + x ) / (CB + X + B )
If you always do what you always did, you'll always get what you always got
