8x=9+7y
Add 7y to both sides.
8x=7y+9
The equation is in standard form.
\frac{8x}{8}=\frac{7y+9}{8}
Divide both sides by 8.
x=\frac{7y+9}{8}
Dividing by 8 undoes the multiplication by 8.
-7y=9-8x
Subtract 8x from both sides.
\frac{-7y}{-7}=\frac{9-8x}{-7}
Divide both sides by -7.
y=\frac{9-8x}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{8x-9}{7}
Divide 9-8x by -7.
