\[ \left \{ y \left ( x \right ) =-{\frac {\cos \left ( x \right ) }{2}}-{\frac {\sin \left ( x \right ) }{2}}-x-1+{{\rm e}^{x}}{\it \_C1} \right \} \] Mathematica raw input
DSolve[y'[x] == x + Sin[x] + y[x],y[x],x]
Mathematica raw output
{{y[x] -> -1 - x + E^x*C[1] - Cos[x]/2 - Sin[x]/2}}
Maple raw input
dsolve(diff(y(x),x) = x+sin(x)+y(x), y(x),'implicit')
Maple raw output
y(x) = -1/2*cos(x)-1/2*sin(x)-x-1+exp(x)*_C1
