3a=1-4b
Subtract 4b from both sides.
\frac{3a}{3}=\frac{1-4b}{3}
Divide both sides by 3.
a=\frac{1-4b}{3}
Dividing by 3 undoes the multiplication by 3.
4b=1-3a
Subtract 3a from both sides.
\frac{4b}{4}=\frac{1-3a}{4}
Divide both sides by 4.
b=\frac{1-3a}{4}
Dividing by 4 undoes the multiplication by 4.
