Does anybody see a problem with this?

Isolate for the variable given. Show all of your work.

A = (B + C) / D
isolate for C


A = (B + C) / D

A * D = B + C

C = A * D – B

Thanks for your help.. :)

Why that looks perfect.
 
Not trying to be stupid, but never forget to use the proper () if you put it in a calculator when it gets longer than this. It can drastically effect your answer. I found out the hard way a while ago... Just a heads up
 
Yeah, more than likely what steve said is your problem.

Multiply each side by D, and subtract by B will always give you the correct equation for C if this is the previous formula..
