For work done in an isobaric process, there is 2 equations equal to each other to find the answer (seen from the photo) but as I used those 2 equations I got 2 different values. Can someone help? 2) There is a phase change from solid to liquid which is isothermal. However, is it also an isobaric process? If not, what is the pressure at the solid state?

1) For work done in an isobaric process, there is 2 equations equal to each other to find the answer (seen from the photo) but as I used those 2 equations I got 2 different values. Can someone help? 2) There is a phase change from solid to liquid which is isothermal. However, is it also an isobaric process? If not, what is the pressure at the solid state?
