```Hello,

I am able to get Mathematica to solve:

Solve[{P1=(a+C*b+b*P2)/(2*b), P2=(a+C*b+b*P1)/(2*b)}, {P1, P2}]

but it won't solve the following (which is one more variable P3 and its equation):

Solve[{P1=(a+C*b+b*P2+b*P3)/(2*b), P2=(a+C*b+b*P1+b*P3)/(2*b), P3=(a+C*b+b*P1+b*P2)/(2*b)}, {P1, P2, P3}]

It says that it doesn't understand how to interpret the word "Solve" even though it does it for the first eqn.

Any help is appreciated.
