-8x=18-5y
Subtract 5y from both sides.
\frac{-8x}{-8}=\frac{18-5y}{-8}
Divide both sides by -8.
x=\frac{18-5y}{-8}
Dividing by -8 undoes the multiplication by -8.
x=\frac{5y}{8}-\frac{9}{4}
Divide 18-5y by -8.
5y=18+8x
Add 8x to both sides.
5y=8x+18
The equation is in standard form.
\frac{5y}{5}=\frac{8x+18}{5}
Divide both sides by 5.
y=\frac{8x+18}{5}
Dividing by 5 undoes the multiplication by 5.
