12x=144-20y
Subtract 20y from both sides.
\frac{12x}{12}=\frac{144-20y}{12}
Divide both sides by 12.
x=\frac{144-20y}{12}
Dividing by 12 undoes the multiplication by 12.
x=-\frac{5y}{3}+12
Divide 144-20y by 12.
20y=144-12x
Subtract 12x from both sides.
\frac{20y}{20}=\frac{144-12x}{20}
Divide both sides by 20.
y=\frac{144-12x}{20}
Dividing by 20 undoes the multiplication by 20.
y=\frac{36-3x}{5}
Divide 144-12x by 20.
