I'm gonna add one to both sides. So I'm gonna add one to both sides. And then what am I going to get if I do that? This is gonna be zero, this is gonna be zero, this is gonna be zero. I'm gonna have two times the derivative of y with respect to x is equal to negative two x minus two y plus one. And now let's see, I can divide everything by two. I would get the derivative of y with respect to x is equal to, and actually, yeah, I would get, I'm just gonna divide by two.
