How do you prove your identity in law?

Example 6: Prove Identity Laws.

To Prove A ∪ ∅ = A Let x ∈ A ∪ ∅ ⇒ x ∈ A or x ∈ ∅ ⇒ x ∈ A (∵x ∈ ∅, as ∅ is the null set ) Therefore, x ∈ A ∪ ∅ ⇒ x ∈ A Hence, A ∪ ∅ ⊂ A. We know that A ⊂ A ∪ B for any set B. But for B = ∅, we have A ⊂ A ∪ ∅ From above, A ⊂ A ∪ ∅ , A ∪ ∅ ⊂ A ⇒ A = A ∪ ∅. Hence Proved.
