\[ \left \{ y \left ( x \right ) ={\it \_C1}\,{{\rm e}^{-bx}}{x}^{-a} \right \} \] Mathematica raw input
DSolve[(a + b*x)*y[x] + x*y'[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> C[1]/(E^(b*x)*x^a)}}
Maple raw input
dsolve(x*diff(y(x),x)+(b*x+a)*y(x) = 0, y(x),'implicit')
Maple raw output
y(x) = _C1*exp(-b*x)*x^(-a)
