-2\times 2m+30=5m
Multiply both sides of the equation by 10, the least common multiple of 5,2.
-4m+30=5m
Multiply -2 and 2 to get -4.
-4m+30-5m=0
Subtract 5m from both sides.
-9m+30=0
Combine -4m and -5m to get -9m.
-9m=-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
m=\frac{-30}{-9}
Divide both sides by -9.
m=\frac{10}{3}
Reduce the fraction \frac{-30}{-9} to lowest terms by extracting and canceling out -3.
