Hi

i am trying to solve the following equation

Solve[1/(1 + Exp[x]) - x == 0, x]

mathematica's reply is this:
Solve::"tdep": "The equations appear to involve the variables to be solved \
for in an essentially non-algebraic way."

another example is:
Solve[ArcTan[x] - x == 0, x]

mathematica gives same reply as above

can anyone help?
thx, romik
