If `y+x(dy)/(dx)=x(varphi(x y))/(varphi^prime(xy))`then`varphi(xy)` is equal to

if y+x(dy)/(dx)=x(phi(xy))/(phi'(xy)) then phi(xy) is equation to

(dy)/(dx)=(xy+y)/(xy+x)

(dy)/(dx)=x^(3)y^(3)-xy

(dy)/(dx)=(y^(2)-x)/(xy+y)

(dy)/(dx)=(x^(2)-y^(2))/(xy)

If the solution of the differential equation x(dy)/(dx)+y=x e^x"b e"x y=e^x & phiv;(x)+c then varphi (x) is equal to

(dy)/(dx)=(x^2y+y)/(xy^2+x)

(dy)/(dx)=xy+2y+x+2

a(x(dy)/(dx)+2y)=xy(dy)/(dx)
