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