\[\left [y \left (x \right ) = \textit {\_C1} \left (a +x \right )^{\frac {a}{a -b}} \left (b +x \right )^{-\frac {b}{a -b}}\right ]\] Mathematica raw input
DSolve[(a + x)*(b + x)*y'[x] == x*y[x],y[x],x]
Mathematica raw output
{{y[x] -> E^((a*Log[a + x] - b*Log[b + x])/(a - b))*C[1]}}
Maple raw input
dsolve((a+x)*(b+x)*diff(y(x),x) = x*y(x), y(x))
Maple raw output
[y(x) = _C1*(a+x)^(a/(a-b))*(b+x)^(-1/(a-b)*b)]
