2buttons + 2buckles = 1/3(11buckles + 3buttons)
6buttons + 6buckles = 11buckles + 3buttons
3buttons = 5buckles

Weight of 3buttons and 2buckles = 5buckles + 2buckles = 7buckles
Weight of 6buttons and 5buckles = 10buckles + 5buckles = 15buckles

(3buttons and 2buckles) = x * (6buttons and 5buckles)
7 = x*15
x = 7/15
