-4x-16=-8y
Subtract 8y from both sides. Anything subtracted from zero gives its negation.
-4x=-8y+16
Add 16 to both sides.
-4x=16-8y
The equation is in standard form.
\frac{-4x}{-4}=\frac{16-8y}{-4}
Divide both sides by -4.
x=\frac{16-8y}{-4}
Dividing by -4 undoes the multiplication by -4.
x=2y-4
Divide -8y+16 by -4.
8y-16=4x
Add 4x to both sides. Anything plus zero gives itself.
8y=4x+16
Add 16 to both sides.
\frac{8y}{8}=\frac{4x+16}{8}
Divide both sides by 8.
y=\frac{4x+16}{8}
Dividing by 8 undoes the multiplication by 8.
y=\frac{x}{2}+2
Divide 16+4x by 8.
