-5m+7=3m-7-2
Combine -7m and 2m to get -5m.
-5m+7=3m-9
Subtract 2 from -7 to get -9.
-5m+7-3m=-9
Subtract 3m from both sides.
-8m+7=-9
Combine -5m and -3m to get -8m.
-8m=-9-7
Subtract 7 from both sides.
-8m=-16
Subtract 7 from -9 to get -16.
m=\frac{-16}{-8}
Divide both sides by -8.
m=2
Divide -16 by -8 to get 2.
