5-1=20m
Variable m cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by m.
4=20m
Subtract 1 from 5 to get 4.
20m=4
Swap sides so that all variable terms are on the left hand side.
m=\frac{4}{20}
Divide both sides by 20.
m=\frac{1}{5}
Reduce the fraction \frac{4}{20} to lowest terms by extracting and canceling out 4.
