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=7y+8
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.
y=\frac{x-8}{7}
Divide 8-x by -7.
