I try to solve the following equation on Mathematica 8

Solve[ p X^(Log[2.0]) + (1 - p) X^(Log[1.6]) ==
p X^(Log[3.85]) + (1 - p) X^(Log[.1]) , X ]

And get the following result :

Solve::inex: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help.

Can someone help me about the meaning of this message ?

Thanks in advance,


NB: I tried to solve the general equation
Solve[ p X^(Log[a]) + (1 - p) X^(Log[b]) ==
pX^(Log[c]) + (1 - p) X^(Log[d]) , X ]
But a get a Solve::nsmet error message. I guess the system is too complicated in the general case ?
