Hello, I am able to get Mathematica to solve: Solve[{P1=(a[1]+C*b[11]+b[12]*P2)/(2*b[11]), P2=(a[2]+C*b[22]+b[21]*P1)/(2*b[22])}, {P1, P2}] but it won't solve the following (which is one more variable P3 and its equation): Solve[{P1=(a[1]+C*b[11]+b[12]*P2+b[13]*P3)/(2*b[11]), P2=(a[2]+C*b[22]+b[21]*P1+b[23]*P3)/(2*b[22]), P3=(a[3]+C*b[33]+b[31]*P1+b[32]*P2)/(2*b[33])}, {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.
