Solve for P
\left\{\begin{matrix}P=\frac{2\left(A+X^{2}\right)}{X}\text{, }&X\neq 0\\P\in \mathrm{R}\text{, }&A=0\text{ and }X=0\end{matrix}\right.
Solve for A
A=\frac{X\left(P-2X\right)}{2}

\frac{PX}{2}-X^{2}=A
Swap sides so that all variable terms are on the left hand side.
\frac{PX}{2}=A+X^{2}
Add X^{2} to both sides.
PX=2A+2X^{2}
Multiply both sides of the equation by 2.
XP=2A+2X^{2}
The equation is in standard form.
\frac{XP}{X}=\frac{2A+2X^{2}}{X}
Divide both sides by X.
P=\frac{2A+2X^{2}}{X}
Dividing by X undoes the multiplication by X.
P=\frac{2\left(A+X^{2}\right)}{X}
Divide 2A+2X^{2} by X.
