Layla and Julie had an equal number of mochi balls at first. After Layla bought another 16 mochi balls and Julie lost 12 mochi balls, Layla had thrice as many mochi balls as Julie. Find the number of mochi balls each of them had at first.

Layla |
Julie |
| Before |
3 u - 16 |
1 u + 12 |
| Change |
+ 16 |
- 12 |
| After |
3 u |
1 u |
The number of mochi balls that Layla and Julie at first is the same.
3 u - 16 = 1 u + 12
3 u - 1 u = 12 + 16
2 u = 28
1 u = 28 ÷ 2 = 14
Number of mochi balls that each of them had at first
= 1 u + 12
= 14 + 12
= 26
Answer(s): 26
