dsolve([-2*y(t)+diff(y(t),t) = exp(2*t),y(0) = 2],y(t), singsol=all)
 
\[ y = \left (2+t \right ) {\mathrm e}^{2 t} \]

Solution by Mathematica

Time used: 0.042 (sec). Leaf size: 14

DSolve[{-2*y[t]+D[y[t],t] == Exp[2*t],y[0]==2},y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to e^{2 t} (t+2) \]
