x+4=-8y
Subtract 8y from both sides. Anything subtracted from zero gives its negation.
x=-8y-4
Subtract 4 from both sides.
8y+4=-x
Subtract x from both sides. Anything subtracted from zero gives its negation.
8y=-x-4
Subtract 4 from both sides.
\frac{8y}{8}=\frac{-x-4}{8}
Divide both sides by 8.
y=\frac{-x-4}{8}
Dividing by 8 undoes the multiplication by 8.
y=-\frac{x}{8}-\frac{1}{2}
Divide -x-4 by 8.
