Mary and Victoria had an equal number of lollipops. After Mary bought another 29 lollipops and Victoria bought another 5 lollipops, Mary had thrice as many lollipops as Victoria. Find the number of lollipops that each of them had at first.

Mary |
Victoria |
| Before |
3 u - 29 |
1 u - 5 |
| Change |
+ 29 |
+ 5 |
| After |
3 u |
1 u |
The number of lollipops that Mary and Victoria had at first is the same.
3 u - 29 = 1 u - 5
3 u - 1 u = 29 - 5
2 u = 24
1 u = 24 ÷ 2 = 12
Number of lollipops that each had at first
= 12 - 5
= 7
Answer(s): 7
