Solve PA=n(4)/7.776

$$P A = \frac { n ( 4 ) } { 7.776 }$$

Solve for A

$$\left\{\begin{matrix}A=\frac{125n}{243P}\text{, }&P\neq 0\\A\in \mathrm{R}\text{, }&n=0\text{ and }P=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Divide n\times 4 by 7.776 to get n\times \frac{125}{243}.

$$PA=n\times \frac{125}{243}$$

The equation is in standard form.

$$PA=\frac{125n}{243}$$

Divide both sides by P.

$$\frac{PA}{P}=\frac{125n}{243P}$$

Dividing by P undoes the multiplication by P.

$$A=\frac{125n}{243P}$$

Solve for P

$$\left\{\begin{matrix}P=\frac{125n}{243A}\text{, }&A\neq 0\\P\in \mathrm{R}\text{, }&n=0\text{ and }A=0\end{matrix}\right.$$
