m^{2}+339-7n=0
Add -3 and 342 to get 339.
339-7n=-m^{2}
Subtract m^{2} from both sides. Anything subtracted from zero gives its negation.
-7n=-m^{2}-339
Subtract 339 from both sides.
\frac{-7n}{-7}=\frac{-m^{2}-339}{-7}
Divide both sides by -7.
n=\frac{-m^{2}-339}{-7}
Dividing by -7 undoes the multiplication by -7.
n=\frac{m^{2}+339}{7}
Divide -m^{2}-339 by -7.
