Hi, not all equations have algebric exact solutions, do you know if this equation has algebric exact solutions ?

Are you sure that your equation is not :

    ln(x + 1) - ln(e^x) = -x + 1

?

Also for Euler's 'e' you need to type <Alt>e to get

not

    e


Try copy & pasting this:

    Solve[ln(x + 1) - ln(ℯ^x) = -x + 1]
