✓ Maple. Time used: 0.001 (sec). Leaf size: 13

ode:=t*diff(y(t),t)+y(t) = t; 
dsolve(ode,y(t), singsol=all);
 

\[ y = \frac {t}{2}+\frac {c_1}{t} \]

✓ Mathematica. Time used: 0.016 (sec). Leaf size: 17

ode=t*D[y[t],t]+y[t]==t; 
ic={}; 
DSolve[{ode,ic},y[t],t,IncludeSingularSolutions->True]
 

\begin{align*} y(t)&\to \frac {t}{2}+\frac {c_1}{t} \end{align*}

from sympy import * 
t = symbols("t") 
y = Function("y") 
ode = Eq(t*Derivative(y(t), t) - t + y(t),0) 
ics = {} 
dsolve(ode,func=y(t),ics=ics)
 

\[ y{\left (t \right )} = \frac {C_{1}}{t} + \frac {t}{2} \]
