-3.2m+7.6+1.3m=0
Add 1.3m to both sides.
-1.9m+7.6=0
Combine -3.2m and 1.3m to get -1.9m.
-1.9m=-7.6
Subtract 7.6 from both sides. Anything subtracted from zero gives its negation.
m=\frac{-7.6}{-1.9}
Divide both sides by -1.9.
m=\frac{-76}{-19}
Expand \frac{-7.6}{-1.9} by multiplying both numerator and the denominator by 10.
m=4
Divide -76 by -19 to get 4.
