The total of beads at first in the 2 scenarios should be equal.
Working Steps:
(1) Start with the number of units in green showing the total of beads is 7 times the number of red beads.
(2) Working backwards to get the number of red beads at first (In red for left side table - 1st scenario)
(3) Use the same (1U + 15) for number of red beads on the right side table - 2nd scenario.
(4) Work out the number of units for the total and blue beads in the right side table.
Hope the explanation is clear.
