15=9b
Variable b cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by b.
9b=15
Swap sides so that all variable terms are on the left hand side.
b=\frac{15}{9}
Divide both sides by 9.
b=\frac{5}{3}
Reduce the fraction \frac{15}{9} to lowest terms by extracting and canceling out 3.
