Two Number Product Calculation
I pick two whole numbers $ x $ and $ y $ between $ 1 $ and $ 10 $ inclusive (not necessarily distinct). My friend picks two numbers $ x -4 $ and $ 2y-1 $. If the product of my friend's numbers is one greater than the product of my numbers, then what is the product of my numbers?
