This paper presents the proofs using Linear Algebra of two Combinatorial theorems, namely the Marriage Theorem and a theorem on Biclique Partitions stated respectively:(1) The sets A1, A2, ..., An possess a system of distinct representatives if and only if, for all k = 1, 2, ..., n, any k sets A1 co...
