45-15x=9y
Swap sides so that all variable terms are on the left hand side.
-15x=9y-45
Subtract 45 from both sides.
\frac{-15x}{-15}=\frac{9y-45}{-15}
Divide both sides by -15.
x=\frac{9y-45}{-15}
Dividing by -15 undoes the multiplication by -15.
x=-\frac{3y}{5}+3
Divide -45+9y by -15.
9y=45-15x
The equation is in standard form.
\frac{9y}{9}=\frac{45-15x}{9}
Divide both sides by 9.
y=\frac{45-15x}{9}
Dividing by 9 undoes the multiplication by 9.
y=-\frac{5x}{3}+5
Divide 45-15x by 9.
