\[\left [y \left (x \right ) = \frac {\left (\frac {a}{x}+\textit {\_C1} \right ) x}{a x +1}\right ]\] Mathematica raw input
DSolve[a - y[x] + x*(1 + a*x)*y'[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> (a + x*C[1])/(1 + a*x)}}
Maple raw input
dsolve(x*(a*x+1)*diff(y(x),x)+a-y(x) = 0, y(x))
Maple raw output
[y(x) = (a/x+_C1)/(a*x+1)*x]
