7x=42-2y
Subtract 2y from both sides.
\frac{7x}{7}=\frac{42-2y}{7}
Divide both sides by 7.
x=\frac{42-2y}{7}
Dividing by 7 undoes the multiplication by 7.
x=-\frac{2y}{7}+6
Divide 42-2y by 7.
2y=42-7x
Subtract 7x from both sides.
\frac{2y}{2}=\frac{42-7x}{2}
Divide both sides by 2.
y=\frac{42-7x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{7x}{2}+21
Divide 42-7x by 2.
