= Solution

Factor out $x$ from the differential expression:
$$
\mathcal Ly=x\left[-(xy')'-\frac yx\right].
$$
Comparing with $\mathcal Ly=w^{-1}[-(py')'+qy]$ gives
$$
\boxed{p(x)=x,\qquad q(x)=-\frac1x,\qquad w(x)=\frac1x.}
$$
Multiplying all three by the same positive constant would give the same <Sturm-Liouville operator>.
