\frac{A_{n}}{min(A_{0})}=S_{2}
Swap sides so that all variable terms are on the left hand side.
\frac{1}{A_{0}}A_{n}=S_{2}
The equation is in standard form.
\frac{\frac{1}{A_{0}}A_{n}A_{0}}{1}=\frac{S_{2}A_{0}}{1}
Divide both sides by A_{0}^{-1}.
A_{n}=\frac{S_{2}A_{0}}{1}
Dividing by A_{0}^{-1} undoes the multiplication by A_{0}^{-1}.
A_{n}=A_{0}S_{2}
Divide S_{2} by A_{0}^{-1}.
