Solve: (dy)/(dx)+y/x=x^n

If y=a\ x^(n+1)+b x^(-n) find (dy)/(dx) .

If x^3+y^3+3a x y=0 , f i n d dy / dx

If x^4+y^4-a^2xy=0 " then find " dy/dx

Statement 1: If e^(xy)+ln(xy)+cos(xy)+5=0, then (dy)/(dx)=-y/x . Statement 2: d/(dx)(xy)=0,y is a function of x implies(dy)/(dx)=-y/x .

(x^2y^3+xy)dy=dx

Solve : (dy)/(dx)=1-xy+y-x

If (dy)/dx = (xy)/(x^2 + y^2), y(1) = 1 and y(x) = e then x =
