Rael and Jack had an equal number of mochi balls at first. After Rael bought another 5 mochi balls and Jack lost 23 mochi balls, Rael had five times as many mochi balls as Jack. Find the number of mochi balls each of them had at first.

Rael |
Jack |
| Before |
5 u - 5 |
1 u + 23 |
| Change |
+ 5 |
- 23 |
| After |
5 u |
1 u |
The number of mochi balls that Rael and Jack at first is the same.
5 u - 5 = 1 u + 23
5 u - 1 u = 23 + 5
4 u = 28
1 u = 28 ÷ 4 = 7
Number of mochi balls that each of them had at first
= 1 u + 23
= 7 + 23
= 30
Answer(s): 30
