Olivia had an equal number of dragonfruits and peaches at first. She sold one-third of the peaches and bought another 14 dragonfruits. In the end, she had five times as many dragonfruits as peaches. Find the number of peaches she had at first.

Dragonfruits |
Peaches |
| Before |
10 u - 14 |
3 u |
| Change |
+ 14 |
- 1 u |
| After |
10 u |
2 u |
The number of dragonfruits and peaches at first is the same.
10 u - 14 = 3 u
10 u - 3 u = 14
7 u = 14
1 u = 14 ÷ 7 = 2
Number of peaches that Olivia had at first
= 3 u
= 3 x 2
= 6
Answer(s): 6
