2a=1-3b
Subtract 3b from both sides.
\frac{2a}{2}=\frac{1-3b}{2}
Divide both sides by 2.
a=\frac{1-3b}{2}
Dividing by 2 undoes the multiplication by 2.
3b=1-2a
Subtract 2a from both sides.
\frac{3b}{3}=\frac{1-2a}{3}
Divide both sides by 3.
b=\frac{1-2a}{3}
Dividing by 3 undoes the multiplication by 3.
