Your answer is 14. Let me explain. X is the same as X/1. Normally, X's reciprocal would be written 1/X. If you multiplied the two, you would have X/1 times 1/X = X/X. Simplify, and you have 1/1 or simply 1. This problem is saying X/1 = 1/Y . Multiply Y times both sides (or cross multiply) and you get XY = 1. Substitute 1 for the XY in your problem, and you get (8 times 1) + 6 = 14. Understand?
