\begin{align*} y^{\prime }+10 y&=2 \,{\mathrm e}^{t} \end{align*}

Solution by Maple

Time used: 0.002 (sec). Leaf size: 20

dsolve(diff(y(t),t)+10*y(t)=2*exp(t),y(t), singsol=all)
 
\[ y = \frac {\left (2 \,{\mathrm e}^{11 t}+11 c_{1} \right ) {\mathrm e}^{-10 t}}{11} \]

Solution by Mathematica

Time used: 0.055 (sec). Leaf size: 21

DSolve[D[y[t],t]+10*y[t]==2*Exp[t],y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to \frac {2 e^t}{11}+c_1 e^{-10 t} \]
