A, U, B are sets and Ø is an empty set. I'm asked to prove that if (U = intersection of A and B) and (intersection of A and B = Ø) then A = U\B. I'm not sure how to begin solving this problem.

You're right, it's supposed to be if (U = union of A and B) and (intersection of A and B = Ø) then A = U\B.
Take note that
