14 of her buttons, Joelle had twice as many buttons as Elyse. How many buttons did Elyse have at first?

Comparing Joelle and
Elyse at first |
6 more |

| Before |
6 u |
4 u |
| Change |

- 1 u |
| After |
6 u |
3 u |
Comparing Joelle and
Elyse in the end |
2x3 =
6 u |
1x3 =
3 u |
Number of buttons that Elyse had in the end is repeated. Make the number of buttons that Elyse had in the end the same. LCM of 1 and 3 is 3.
Number of buttons that Joelle had at first = 6 u
Number of buttons that Joelle had more than Elyse at first
= 6 u - 4 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Number of buttons that Elyse had at first
= 4 u
= 4 x 3
= 12
Answer(s): 12
