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