**Use an element argument to prove each statement in 7-22. Assume that all sets are subsets of a universal set ****U.**

For all sets *A*,*B*, and *C*,

To determine

**To prove:**

For all sets

**Given information:**

**Concept used:**

**Calculation:**

Let

Prove that

First prove that

Suppose there is an element

Case 1.

If

Since

Thus,

Hence,

Case 2.

If

Since

Thus,

Hence

Therefore, both the cases yields
