Help me isolate b!

1/a+1/b=1/c i have to isolate b, how do i do that?

 

\(\color{Mahogany}\frac{1}{a}+\frac{1}{b}=\frac{1}{c}\\ \frac{1}{b}=\frac{1}{c}-\frac{1}{a}\\ \frac{1}{b}=\frac{a-c}{ac}\)           \(\large -\frac{1}{a}\\ common\ denominator\\ reciprocal\)  

 

\(\large b=\frac{ac}{a-c}\)
