Is it possible to prove this set inequality given the constraints?

1. The problem statement, all variables and given/known data

2. Relevant equations

I have to use these set identities:

3. The attempt at a solution

Pretty sure this is impossible since it's an inequality.

I thunk you can convert the inequality in two equalities with the right set and theorem 6.2.3.

Nice, I proved it using this and it only took 19 steps.
