7a=c-3b
Subtract 3b from both sides.
\frac{7a}{7}=\frac{c-3b}{7}
Divide both sides by 7.
a=\frac{c-3b}{7}
Dividing by 7 undoes the multiplication by 7.
3b=c-7a
Subtract 7a from both sides.
\frac{3b}{3}=\frac{c-7a}{3}
Divide both sides by 3.
b=\frac{c-7a}{3}
Dividing by 3 undoes the multiplication by 3.
