Neave and Pamela had the same number of mochi balls. After Pamela gave away 19 mochi balls and Neave gave away 38 mochi balls, Pamela had 2 times as many mochi balls as Neave. How many mochi balls did each of them have at first?
| |
Neave |
Pamela |
| Before |
1 u + 38 |
2 u + 19 |
| Change |
- 38 |
- 19 |
| After |
1 u |
2 u |
The number of mochi balls that Neave and Pamela had at first is the same.
2 u + 19 = 1 u + 38
2 u - 1 u = 38 - 19
1 u = 19
1 u = 19 ÷ 1 = 19
Number of mochi balls that each of them had at first
= 1 u + 38
= 19 + 38
= 57
Answer(s): 57
