3x=21-2y
Subtract 2y from both sides.
\frac{3x}{3}=\frac{21-2y}{3}
Divide both sides by 3.
x=\frac{21-2y}{3}
Dividing by 3 undoes the multiplication by 3.
x=-\frac{2y}{3}+7
Divide 21-2y by 3.
2y=21-3x
Subtract 3x from both sides.
\frac{2y}{2}=\frac{21-3x}{2}
Divide both sides by 2.
y=\frac{21-3x}{2}
Dividing by 2 undoes the multiplication by 2.
