29a=90b
Multiply both sides of the equation by 6b.
\frac{29a}{29}=\frac{90b}{29}
Divide both sides by 29.
a=\frac{90b}{29}
Dividing by 29 undoes the multiplication by 29.
29a=90b
Variable b cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 6b.
90b=29a
Swap sides so that all variable terms are on the left hand side.
\frac{90b}{90}=\frac{29a}{90}
Divide both sides by 90.
b=\frac{29a}{90}
Dividing by 90 undoes the multiplication by 90.
b=\frac{29a}{90}\text{, }b\neq 0
Variable b cannot be equal to 0.
