125n+15750=C
Swap sides so that all variable terms are on the left hand side.
125n=C-15750
Subtract 15750 from both sides.
\frac{125n}{125}=\frac{C-15750}{125}
Divide both sides by 125.
n=\frac{C-15750}{125}
Dividing by 125 undoes the multiplication by 125.
n=\frac{C}{125}-126
Divide C-15750 by 125.
