4x=16-8y
Subtract 8y from both sides.
\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=4-2y
Divide 16-8y by 4.
8y=16-4x
Subtract 4x from both sides.
\frac{8y}{8}=\frac{16-4x}{8}
Divide both sides by 8.
y=\frac{16-4x}{8}
Dividing by 8 undoes the multiplication by 8.
y=-\frac{x}{2}+2
Divide 16-4x by 8.
