91bc=2R^{2}\times 60
Multiply both sides of the equation by 364R^{2}, the least common multiple of 2R\times 2R,182.
91bc=120R^{2}
Multiply 2 and 60 to get 120.
91cb=120R^{2}
The equation is in standard form.
\frac{91cb}{91c}=\frac{120R^{2}}{91c}
Divide both sides by 91c.
b=\frac{120R^{2}}{91c}
Dividing by 91c undoes the multiplication by 91c.
