11x=12-31y
Subtract 31y from both sides.
\frac{11x}{11}=\frac{12-31y}{11}
Divide both sides by 11.
x=\frac{12-31y}{11}
Dividing by 11 undoes the multiplication by 11.
31y=12-11x
Subtract 11x from both sides.
\frac{31y}{31}=\frac{12-11x}{31}
Divide both sides by 31.
y=\frac{12-11x}{31}
Dividing by 31 undoes the multiplication by 31.
