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=(P)/(1)\\---------------\\P=(2)/(A)\ \ \ Domain:A\\eq0\\\\(P)/(1)=(2)/(A)\ \ \ \ |cross\ multiply\\\\P\cdot A=1\cdot2\ \ \ \ |divide\ both\ sides\ by\ P\\eq0\\\\\boxed{A=(2)/(P)}`
