8x=330-4y
Subtract 4y from both sides.
\frac{8x}{8}=\frac{330-4y}{8}
Divide both sides by 8.
x=\frac{330-4y}{8}
Dividing by 8 undoes the multiplication by 8.
x=-\frac{y}{2}+\frac{165}{4}
Divide 330-4y by 8.
4y=330-8x
Subtract 8x from both sides.
\frac{4y}{4}=\frac{330-8x}{4}
Divide both sides by 4.
y=\frac{330-8x}{4}
Dividing by 4 undoes the multiplication by 4.
y=\frac{165}{2}-2x
Divide 330-8x by 4.
