The Nineteenth Byte

Hey everyone I have a question about deconstructing this conditional probability. After using Bayes Rule and then attempting to use P(A | B,C) = P(A,B | B,C) and P(A|B,C) = P(A,B | C)/P(B|C) I can not for the life of me figure out how to make both sides equal. Thank You PS First time poster s...
