\[ \left \{ x+{\frac {by \left ( x \right ) }{1+a}}- \left ( y \left ( x \right ) \right ) ^{-a}{\it \_C1}=0 \right \} \] Mathematica raw input
DSolve[y[x] + (a*x + b*y[x])*y'[x] == 0,y[x],x]
Mathematica raw output
Solve[Log[x] + (a*Log[y[x]/x] + Log[1 + a + (b*y[x])/x])/(1 + a) == C[1], y[x]]
Maple raw input
dsolve((a*x+b*y(x))*diff(y(x),x)+y(x) = 0, y(x),'implicit')
Maple raw output
x+b/(1+a)*y(x)-y(x)^(-a)*_C1 = 0
