The general solution of the differential equation y '= Y / x + e ^ (Y / x) is

The general solution of the differential equation y '= Y / x + e ^ (Y / x) is

Let Y / x = U,
Then y '= (Xu)' = u + Xu '
Substituting into the original equation: U + Xu '= u + e ^ u
xdu/dx=e^u
du/e^u=dx/x
-e^(-u)=lnx+c1
-e^(-y/x)=lnx+c1
y=-xln(c-lnx)
