4a=26-5b
Subtract 5b from both sides.
\frac{4a}{4}=\frac{26-5b}{4}
Divide both sides by 4.
a=\frac{26-5b}{4}
Dividing by 4 undoes the multiplication by 4.
a=-\frac{5b}{4}+\frac{13}{2}
Divide 26-5b by 4.
5b=26-4a
Subtract 4a from both sides.
\frac{5b}{5}=\frac{26-4a}{5}
Divide both sides by 5.
b=\frac{26-4a}{5}
Dividing by 5 undoes the multiplication by 5.
