Question

how do i solve for A.
P= 2/A

Answer 1

P=2/A
multiply both sides by A
PA=2 times A/A
PA=2 times 1
PA=2
divide both sides by P
A=2/P

Answer 2

$P=\frac{P}{1}\\---------------\\P=\frac{2}{A}\ \ \ Domain:A\neq0\\\\\frac{P}{1}=\frac{2}{A}\ \ \ \ |cross\ multiply\\\\P\cdot A=1\cdot2\ \ \ \ |divide\ both\ sides\ by\ P\neq0\\\\\boxed{A=\frac{2}{P}}$
