1st day
A: 5u
B: 4u
total = 9u
2nd day
A: 5u - 14 or 3u
B: 4u + 14 or 6u
(5u - 14) . 2 = 4u + 14
10u - 28 = 4u + 14
1u = 7
OR
5u - 14 = 3u
1u = 7
day 1 , A has 35
*note: total remains unchanged

The total number of students are the same on the 1st and 2nd day, so make the number of units equal (9 units)
