Note that if $y$ is isolated, this is effectively the same as explicit differentiation. When differentiating implicitly, it must be shown that the derivative of both sides with respect to x ($\frac{d}{dx}$) is being taken. !!! warning The **chain rule** must be applied when differentiating terms that contain $y$.
