Then x ∈ A ∩ B and x ∈ A \ B, so x ∈ A and x ∈ B, and x ∈ A and x /∈ B. In particular, this implies x ∈ B and x /∈ B, which is a contradiction. I.e., there can be no such x and we proved that (A∩B)∩(A\B) = ∅. For the set equality, let x ∈ A be arbitrary. Then either x ∈ B or x /∈ B. rainsville golf \u0026 country club
