So this simplifies to 2y minus 2x minus 1 times the derivative of y with respect to x, which is going to be equal to, on this side, this cancels out. We are left with 1 minus 2x plus 2y. So let me write it that way. We could write this as negative 2y is just a positive 2y. And then we have minus 2x. And then we add that 1 plus 1. And now to solve for dy dx, we just have to divide both sides by 2y minus 2x minus 1.
