    How can I solve this differential equation?

    The differential equation is:

    y'xlnx + y(lnx + 1) = 1

    for x > 1


    How can I simplify this?

    Thanks

    Setting \ln x = t the DE becomes...

    \displaystyle t\ \frac{dy}{dt} + (1+t)\ y = 1 (1)

    ... the solution of which is a 'standard job'...

    Kind regards
