Please help. Trying to isolate a variable and I'm stuck.

**vorsilva** · July 10th 2009, 06:08 AM

I was given an equation and asked to solve for C. I've been able to simplify it to

B(AC)=A-C

I can't seem to get any further. Can anyone offer some suggestions?

You need to break the variable out of the multiple term on the LHS...

$BAC=A-C$
$C(BA)=A-C$

Now, group the terms with C's on one side, and the terms without C's on the other side.

$C(BA)+C=A$

Factor out C on the LHS, and divide the equality by the other factor, and you will get your answer. Practice this with many other forms of multiples, divisions, additions, and subtractions.

Would that be

$C(BA-1)=A$
$<br /> C=\frac{A}{BA+1}$

Thanks Skeeter
