How to Calculate Equilibrium Pressures in a Chemical Reaction?

[Questions999]

Reacton between the substances is A+B--> 2C where Pa=3 atm,Pb=2 atm.The reaction moves to the right until 70 percent of B has reacted and we have the equilibrum.FFind Pa,Pb,Pc and the constant of equilibrum

Pa Pb Pc

So in the beginning 3 2 0

The change - x -x +2x How do I find Pa ,Pb and Pc here?

You are told that 70% of B has reacted...
