Work Equation, changing V and P

This relates to midterm 2013 question 4 part A in back of course reader

Why is it that when volume and pressure are both changing that work can equal:

w=-nRTln(V2/V1) or w=-nRTln (P1/P2)


Is it because the pressure is inversely related to the volume?

Yes, that reasoning makes sense.

Yes, Boyle's law states that at a constant temperature, the volume of a fixed amount of gas is inversely proportional to the pressure. In other words, V∝1/P.
