8-x=7y
Swap sides so that all variable terms are on the left hand side.
-x=7y-8
Subtract 8 from both sides.
\frac{-x}{-1}=\frac{7y-8}{-1}
Divide both sides by -1.
x=\frac{7y-8}{-1}
Dividing by -1 undoes the multiplication by -1.
x=8-7y
Divide 7y-8 by -1.
7y=8-x
The equation is in standard form.
\frac{7y}{7}=\frac{8-x}{7}
Divide both sides by 7.
y=\frac{8-x}{7}
Dividing by 7 undoes the multiplication by 7.
