8.5+0.5m=9m
Combine -1.5m and 2m to get 0.5m.
8.5+0.5m-9m=0
Subtract 9m from both sides.
8.5-8.5m=0
Combine 0.5m and -9m to get -8.5m.
-8.5m=-8.5
Subtract 8.5 from both sides. Anything subtracted from zero gives its negation.
m=\frac{-8.5}{-8.5}
Divide both sides by -8.5.
m=1
Divide -8.5 by -8.5 to get 1.
