12x=300-15y
Subtract 15y from both sides.
\frac{12x}{12}=\frac{300-15y}{12}
Divide both sides by 12.
x=\frac{300-15y}{12}
Dividing by 12 undoes the multiplication by 12.
x=-\frac{5y}{4}+25
Divide 300-15y by 12.
15y=300-12x
Subtract 12x from both sides.
\frac{15y}{15}=\frac{300-12x}{15}
Divide both sides by 15.
y=\frac{300-12x}{15}
Dividing by 15 undoes the multiplication by 15.
y=-\frac{4x}{5}+20
Divide 300-12x by 15.
