(y∧z)∨(y∧(¬z))∨(¬(x∨z))∨(¬(x∨(¬z)))
$$\left(y \wedge z\right) \vee \left(y \wedge \neg z\right) \vee \neg \left(x \vee z\right) \vee \neg \left(x \vee \neg z\right)$$
Solución detallada
$$\neg \left(x \vee z\right) = \neg x \wedge \neg z$$
$$\neg \left(x \vee \neg z\right) = z \wedge \neg x$$
$$\left(y \wedge z\right) \vee \left(y \wedge \neg z\right) \vee \neg \left(x \vee z\right) \vee \neg \left(x \vee \neg z\right) = y \vee \neg x$$
$$\neg \left(x \vee \neg z\right) = z \wedge \neg x$$
$$\left(y \wedge z\right) \vee \left(y \wedge \neg z\right) \vee \neg \left(x \vee z\right) \vee \neg \left(x \vee \neg z\right) = y \vee \neg x$$
