24x=18+2y
Add 2y to both sides.
24x=2y+18
The equation is in standard form.
\frac{24x}{24}=\frac{2y+18}{24}
Divide both sides by 24.
x=\frac{2y+18}{24}
Dividing by 24 undoes the multiplication by 24.
x=\frac{y}{12}+\frac{3}{4}
Divide 18+2y by 24.
-2y=18-24x
Subtract 24x from both sides.
\frac{-2y}{-2}=\frac{18-24x}{-2}
Divide both sides by -2.
y=\frac{18-24x}{-2}
Dividing by -2 undoes the multiplication by -2.
y=12x-9
Divide 18-24x by -2.
