Shiyun had 58 more jelly beans than Elyse. Shiyun used
78 of her jelly beans and Elyse used
23 of her jelly beans. In the end, Shiyun had 4 times as much as Elyse. Find the number of jelly beans that Elyse had at first.

8x4 =
32 u |
3 u |
| Change |
- 7x4 =
- 28 u |
- 2 u |
| After |
1x4 =
4 u |
1 u |
Comparing Shiyun
and Parry in the end |
4 u |
1 u |
The number of jelly beans that Shiyun had in the end is repeated. Make the number of jelly beans that Shiyun had in the end the same. LCM of 1 and 4 is 4.
Number of jelly beans that Shiyun had more than Elyse
= 32 u - 3 u
= 29 u
29 u = 58
1 u = 58 ÷ 29 = 2
Number of jelly beans that Elyse had at first
= 3 u
= 3 x 2
= 6
Answer(s): 6
