Flynn and George had the same number of beads. Flynn gave away
57 of his beads while George gave away
35 of his beads. Given that Flynn gave away 12 beads more than George, how many beads did Flynn have at first?

Flynn's beads |
George's beads |
| Before |
7x5 =
35 u |
5x7 =
35 u |
| Change |
- 5x5 =
- 25 u |
- 3x7 =
- 21 u |
| After |
2x5 =
10 u |
2x7 =
14 u |
The number of cards that Flynn and George each had at first is the same. Make the number of cards that Flynn and George each had at first the same. LCM of 7 and 5 is 35.
Number of beads that Flynn gave away more than George
= 25 u - 21 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of beads that Flynn had at first
= 35 u
= 35 x 3
= 105
Answer(s): 105
