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