| Before |
4 u - 17 |
1 u + 22 |
| Change |
+ 17 |
- 22 |
| After |
4 u |
1 u |
The number of mochi balls that Matthew and Jeremiah at first is the same.
4 u - 17 = 1 u + 22
4 u - 1 u = 22 + 17
3 u = 39
1 u = 39 ÷ 3 = 13
Number of mochi balls that each of them had at first
= 1 u + 22
= 13 + 22
= 35
Answer(s): 35
