Typically you know three out of the four variables and solve for the last variable.
But sometimes they get tricky by giving you only two but one of the remaining variable is related to one or two of the given variables.

Separate the problem data into before the experiment and after the experiment.
Then plug the information into your equation.
Also, know your units for pressure and for volume. It will help you in the long run when working any type of chemistry or physics problems.
It nice thing about this equation is that you don't have to convert your units to something specific. Just make sure either the 2 pressures are the same or the 2 volumes are the same, depending on what is being asked.

say you have inital pressure 760atm and volume 5 l what is the final volume if the final pressure is raised to 790 atm.
p1 = 760 atm
v1 = 5 l
p2 = 790 atm
v2 = ? find v2

These are simple algebra problems. You stated the formula in your question.
(P1)(V1) = (P2)(V2)
Plug in what you know and solve for what you don't know.
ex) P1 = 100 psi
V1 = 1 liter
P2= 200 psi
(100)(1) = (200)(V2)
V2 = 0.5 liters

You get three pieces of data, say P1, V1, P2 and find the missing one, V2.
