5\times 4-2\times 2=30m
Variable m cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10m, the least common multiple of 2m,5m.
20-4=30m
Do the multiplications.
16=30m
Subtract 4 from 20 to get 16.
30m=16
Swap sides so that all variable terms are on the left hand side.
m=\frac{16}{30}
Divide both sides by 30.
m=\frac{8}{15}
Reduce the fraction \frac{16}{30} to lowest terms by extracting and canceling out 2.
