Let's do that. We can add two x to both sides. And we would get two y times the derivative of y with respect to x is equal to two x. And now I can divide both sides by two y. And I am going to get that the derivative of y with respect to x is equal to x, x over y. Now, the next step is let's take the derivative of both sides of this with respect to x. And then we can hopefully find our second derivative of y with respect to x.
