CAS Maple gives this as type [y=_G(x,y')]

Solve \begin {gather*} \boxed {y^{\prime }-y-{\mathrm e}^{-y}-{\mathrm e}^{-t}=0} \end {gather*}

Solution by Maple

dsolve(diff(y(t),t)= y(t)+exp(-y(t))+exp(-t),y(t), singsol=all)
 

\[ \text {No solution found} \]

Solution by Mathematica

Time used: 0.0 (sec). Leaf size: 0

DSolve[y'[t]== y[t]+Exp[-y[t]]+Exp[-t],y[t],t,IncludeSingularSolutions -> True]
