5m+6+2m+15+7>0
Combine m^{2} and -m^{2} to get 0.
7m+6+15+7>0
Combine 5m and 2m to get 7m.
7m+21+7>0
Add 6 and 15 to get 21.
7m+28>0
Add 21 and 7 to get 28.
7m>-28
Subtract 28 from both sides. Anything subtracted from zero gives its negation.
m>\frac{-28}{7}
Divide both sides by 7. Since 7 is positive, the inequality direction remains the same.
m>-4
Divide -28 by 7 to get -4.
