    dy/dx problem

    I am having some trouble with this quesetion.

    Find dy/dx if x^2y=e^(x+y)

    What I have is

    x^2*dy/dx + y*2x=e^(x+y) 1+dy/dx

    x^2 dy/dx + 2xy = (1+dy/dx) e^x+y

    after this, this where I do don't know how to take out the dy/dx

    Move everything around so that dy\dx is on one side by itself.
    Then solve by factoring out the dy/dx and divide.
