2a=20-3b
Subtract 3b from both sides.
\frac{2a}{2}=\frac{20-3b}{2}
Divide both sides by 2.
a=\frac{20-3b}{2}
Dividing by 2 undoes the multiplication by 2.
a=-\frac{3b}{2}+10
Divide 20-3b by 2.
3b=20-2a
Subtract 2a from both sides.
\frac{3b}{3}=\frac{20-2a}{3}
Divide both sides by 3.
b=\frac{20-2a}{3}
Dividing by 3 undoes the multiplication by 3.
