30m+15=20m-12
Multiply both sides of the equation by 60, the least common multiple of 2,4,3,5.
30m+15-20m=-12
Subtract 20m from both sides.
10m+15=-12
Combine 30m and -20m to get 10m.
10m=-12-15
Subtract 15 from both sides.
10m=-27
Subtract 15 from -12 to get -27.
m=\frac{-27}{10}
Divide both sides by 10.
m=-\frac{27}{10}
Fraction \frac{-27}{10} can be rewritten as -\frac{27}{10} by extracting the negative sign.
