I've written the following task:
equations = {Ca == 2c, 1/Cb == 1/c + 1/(3 c), 1/Cc == 1/c + 1/(3 c), Cd == 2, Ce == Ca + Cb + Cd};
Solve[equations, Ca]
Solve[equations, Cb]
Solve[equations, Cc]
Solve[equations, Cd]
Solve[equations, Ce]
And after processing this input, i get solution only for Ce and Cc, while other solutions are empty.
The solutions are obvious, however exept for enumerated above Mathematica reports "{}", that means "no solutions".
Why is that? Am I doing something wrong?
Thank everyone for assistance.
