Solve for b
\left\{\begin{matrix}b=\frac{R}{h^{2}}\text{, }&h\neq 0\\b\in \mathrm{R}\text{, }&R=0\text{ and }h=0\end{matrix}\right.
Solve for R
R=bh^{2}

bh^{2}=R
Swap sides so that all variable terms are on the left hand side.
h^{2}b=R
The equation is in standard form.
\frac{h^{2}b}{h^{2}}=\frac{R}{h^{2}}
Divide both sides by h^{2}.
b=\frac{R}{h^{2}}
Dividing by h^{2} undoes the multiplication by h^{2}.
