13x+12x_{12}=65520
Combine x and 12x to get 13x.
13x=65520-12x_{12}
Subtract 12x_{12} from both sides.
\frac{13x}{13}=\frac{65520-12x_{12}}{13}
Divide both sides by 13.
x=\frac{65520-12x_{12}}{13}
Dividing by 13 undoes the multiplication by 13.
x=-\frac{12x_{12}}{13}+5040
Divide 65520-12x_{12} by 13.
13x+12x_{12}=65520
Combine x and 12x to get 13x.
12x_{12}=65520-13x
Subtract 13x from both sides.
\frac{12x_{12}}{12}=\frac{65520-13x}{12}
Divide both sides by 12.
x_{12}=\frac{65520-13x}{12}
Dividing by 12 undoes the multiplication by 12.
x_{12}=-\frac{13x}{12}+5460
Divide 65520-13x by 12.
