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