\begin{align*} y^{\prime }-y&=2 \,{\mathrm e}^{t} \end{align*}

Solution by Maple

Time used: 0.001 (sec). Leaf size: 12

dsolve(diff(y(t),t)-y(t)=2*exp(t),y(t), singsol=all)
 
\[ y = \left (2 t +c_{1} \right ) {\mathrm e}^{t} \]

Solution by Mathematica

Time used: 0.040 (sec). Leaf size: 15

DSolve[D[y[t],t]-y[t]==2*Exp[t],y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to e^t (2 t+c_1) \]
