Hazel and Emma had an equal number of lollipops at first. After Hazel bought another 20 lollipops and Emma lost 30 lollipops, Hazel had thrice as many lollipops as Emma. Find the number of lollipops each of them had at first.

Hazel |
Emma |
| Before |
3 u - 20 |
1 u + 30 |
| Change |
+ 20 |
- 30 |
| After |
3 u |
1 u |
The number of lollipops that Hazel and Emma at first is the same.
3 u - 20 = 1 u + 30
3 u - 1 u = 30 + 20
2 u = 50
1 u = 50 ÷ 2 = 25
Number of lollipops that each of them had at first
= 1 u + 30
= 25 + 30
= 55
Answer(s): 55
