    The total number of bagles = 12*(the number of 12 bagel bags) + 6*(the number of 6 bagel bags)

    20 = (the number of 12 bagel bags) + (the number of 6 bagel bags)

    divide the total by 12 and get 14 bags of 12. this is shoert of the 20 you need. then just understand for every i bag of twelve you take away you add to bags of six. this leads you to knocking the 14 bags of twelve to 8 bags of 12 and giving you 8 bags or 6. This gives you your 20 bags and your 168 bagels
