| |
Harry |
Oscar |
| Before |
1 u + 21 |
5 u + 13 |
| Change |
- 21 |
- 13 |
| After |
1 u |
5 u |
Harry and Oscar had an equal number of lollipops at first.
5 u + 13 = 1 u + 21
5 u - 1 u = 21 - 13
4 u = 8
1 u = 8 ÷ 4 = 2
Number of lollipops that each of them had at first
= 1 u + 21
= 2 + 21
= 23
Answer(s): 23
