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

Will's marbles |
Flynn's marbles |
| Before |
4x5 =
20 u |
5x4 =
20 u |
| Change |
- 3x5 =
- 15 u |
- 3x4 =
- 12 u |
| After |
1x5 =
5 u |
2x4 =
8 u |
The number of cards that Will and Flynn each had at first is the same. Make the number of cards that Will and Flynn each had at first the same. LCM of 4 and 5 is 20.
Number of marbles that Will gave away more than Flynn
= 15 u - 12 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of marbles that Will had at first
= 20 u
= 20 x 4
= 80
Answer(s): 80
