2-5=30\mu
Variable \mu cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10\mu , the least common multiple of 5\mu ,2\mu .
-3=30\mu
Subtract 5 from 2 to get -3.
30\mu =-3
Swap sides so that all variable terms are on the left hand side.
\mu =\frac{-3}{30}
Divide both sides by 30.
\mu =-\frac{1}{10}
Reduce the fraction \frac{-3}{30} to lowest terms by extracting and canceling out 3.
