\[ \boxed { {\frac {\rm d}{{\rm d}x}}y \left ( x \right ) = \left ( -\ln \left ( y \left ( x \right ) \right ) +x \right ) y \left ( x \right ) =0} \]
Mathematica: cpu = 0.038505 (sec), leaf count = 20 \[ \left \{\left \{y(x)\to e^{-e^{c_1-x}+x-1}\right \}\right \} \]
Maple: cpu = 0.110 (sec), leaf count = 14 \[ \left \{ y \left ( x \right ) ={{\rm e}^{{\frac {{\it \_C1}}{{{\rm e}^{x }}}}-1+x}} \right \} \]
