14a=5-2b
Subtract 2b from both sides.
\frac{14a}{14}=\frac{5-2b}{14}
Divide both sides by 14.
a=\frac{5-2b}{14}
Dividing by 14 undoes the multiplication by 14.
a=-\frac{b}{7}+\frac{5}{14}
Divide 5-2b by 14.
2b=5-14a
Subtract 14a from both sides.
\frac{2b}{2}=\frac{5-14a}{2}
Divide both sides by 2.
b=\frac{5-14a}{2}
Dividing by 2 undoes the multiplication by 2.
b=\frac{5}{2}-7a
Divide 5-14a by 2.
