50-10m=2.5m+12.5
Use the distributive property to multiply m+5 by 2.5.
50-10m-2.5m=12.5
Subtract 2.5m from both sides.
50-12.5m=12.5
Combine -10m and -2.5m to get -12.5m.
-12.5m=12.5-50
Subtract 50 from both sides.
-12.5m=-37.5
Subtract 50 from 12.5 to get -37.5.
m=\frac{-37.5}{-12.5}
Divide both sides by -12.5.
m=\frac{-375}{-125}
Expand \frac{-37.5}{-12.5} by multiplying both numerator and the denominator by 10.
m=3
Divide -375 by -125 to get 3.
