Emily and Joshua had an equal number of lollipops at first. After Emily bought another 11 lollipops and Joshua lost 15 lollipops, Emily had thrice as many lollipops as Joshua. Find the number of lollipops each of them had at first.

Emily |
Joshua |
| Before |
3 u - 11 |
1 u + 15 |
| Change |
+ 11 |
- 15 |
| After |
3 u |
1 u |
The number of lollipops that Emily and Joshua at first is the same.
3 u - 11 = 1 u + 15
3 u - 1 u = 15 + 11
2 u = 26
1 u = 26 ÷ 2 = 13
Number of lollipops that each of them had at first
= 1 u + 15
= 13 + 15
= 28
Answer(s): 28
