DSolve[-x + y[x] + x^2*Derivative[1][y][x] == 0,y[x],x]
 
\[\left \{\left \{y(x)\to -e^{\frac {1}{x}} \text {Ei}\left (-\frac {1}{x}\right )+c_1 e^{\frac {1}{x}}\right \}\right \}\]

Maple : cpu = 0.014 (sec), leaf count = 16

dsolve(x^2*diff(y(x),x)+y(x)-x = 0,y(x))
 
\[y \left (x \right ) = \left (\operatorname {Ei}_{1}\left (\frac {1}{x}\right )+c_{1} \right ) {\mathrm e}^{\frac {1}{x}}\]
