Solution by Maple

Time used: 0.125 (sec). Leaf size: 36

dsolve(x^6*diff(y(x),x)^3-x*diff(y(x),x)-y(x) = 0,y(x), singsol=all)
 

\begin{align*} y \left (x \right ) &= -\frac {2 \sqrt {3}}{9 x^{\frac {3}{2}}} \\ y \left (x \right ) &= \frac {2 \sqrt {3}}{9 x^{\frac {3}{2}}} \\ y \left (x \right ) &= c_{1}^{3}-\frac {c_{1}}{x} \\ \end{align*}
