Solución
Solución detallada
$$x \Rightarrow \left(y \vee \neg z\right) = y \vee \neg x \vee \neg z$$
$$x \not\Rightarrow \left(y \vee \neg z\right) = x \wedge z \wedge \neg y$$
$$\neg z ⇔ x \not\Rightarrow \left(y \vee \neg z\right) = z \wedge \left(y \vee \neg x\right)$$
$$z \wedge \left(y \vee \neg x\right)$$
