HI HELP!!!!! If you are the first to figure it out i will give you the Brainlyist I promise . 6 piles of marbles are arranged in a triangle pattern. Each side of the triangle has a total of 9 marbles. Add 1 more marble to one of the piles, so that the total number of marbles on each side remains 9. You are allowed to move the marbles but not take any out.
The key is to move 1 marble from 1 corner to a side. For example, move 1 marble from pile A to pile B. The bottom side of the triangle only has 8 marbles left. Add 1 marble to pile C, all 3 sides still have 9 marbles.
