\[ \left \{ y \left ( x \right ) =\sqrt {{x}^{2}+1}{\it \_C1}-ax \right \} \] Mathematica raw input
DSolve[a - x*y[x] + (1 + x^2)*y'[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> -(a*x) + Sqrt[1 + x^2]*C[1]}}
Maple raw input
dsolve((x^2+1)*diff(y(x),x)+a-x*y(x) = 0, y(x),'implicit')
Maple raw output
y(x) = (x^2+1)^(1/2)*_C1-a*x
