Solution by Maple

Time used: 0.001 (sec). Leaf size: 13

dsolve(y(x)+3*x*diff(y(x),x) = 12*x,y(x), singsol=all)
 

\[ y \relax (x ) = 3 x +\frac {c_{1}}{x^{\frac {1}{3}}} \]

Solution by Mathematica

Time used: 0.025 (sec). Leaf size: 17

DSolve[y[x]+3*x*y'[x] == 12*x,y[x],x,IncludeSingularSolutions -> True]
 

\begin{align*} y(x)\to 3 x+\frac {c_1}{\sqrt [3]{x}} \\ \end{align*}
