\begin{align*} y^{\prime }+2 y&=3 x \end{align*}

Solution by Maple

Time used: 0.002 (sec). Leaf size: 15

dsolve(diff(y(x),x)+2*y(x)=3*x,y(x), singsol=all)
 
\[ y = \frac {3 x}{2}-\frac {3}{4}+c_{1} {\mathrm e}^{-2 x} \]

Solution by Mathematica

Time used: 0.041 (sec). Leaf size: 22

DSolve[D[y[x],x]+2*y[x]==3*x,y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \frac {3 x}{2}+c_1 e^{-2 x}-\frac {3}{4} \]
