Hey guys, so I got a math question for a computer science course, this one is giving me a bit of trouble Can anyone point me in the correct direction?

Prove that:

A n B is a subset of (A n C) u ( B n C') without the use of set algebra.

n - intersection
u - union
A - set a
B - set b
C' - C compliment.

All input is appreciated.

Im poor at sets, but try drawing Venn Diagrams! That helps a lot.

Wish I could draw them, but it's a proof and drawing diagrams is not a proof. Managed to get it out using proof by contradiction.
