7x=4-8y
Subtract 8y from both sides.
\frac{7x}{7}=\frac{4-8y}{7}
Divide both sides by 7.
x=\frac{4-8y}{7}
Dividing by 7 undoes the multiplication by 7.
8y=4-7x
Subtract 7x from both sides.
\frac{8y}{8}=\frac{4-7x}{8}
Divide both sides by 8.
y=\frac{4-7x}{8}
Dividing by 8 undoes the multiplication by 8.
y=-\frac{7x}{8}+\frac{1}{2}
Divide 4-7x by 8.
