" (a) "x(dy)/(dx)-y=x+y(dy)/(dx)

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

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

(dy)/(dx)=x+y

If y=xlog(x/(a+b x)),t h e nx^3(d^2y)/(dx^2)= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^2 y(dy)/(dx)-x (d) (y(dy)/(dx)-x)^2

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

If y=x log((x)/(a+bx)), thenx ^(3)(d^(2)y)/(dx^(2))= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^(2)y(dy)/(dx)-x(d)(y(dy)/(dx)-x)^(2)

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

Solve : y^(2)-x(dy)/(dx)=a(y+(dy)/(dx))

Solve: y-x(dy)/(dx)=x+y(dy)/(dx)
