Lily and Noah had an equal number of mini cupcakes at first. After Lily bought another 16 mini cupcakes and Noah lost 12 mini cupcakes, Lily had five times as many mini cupcakes as Noah. Find the number of mini cupcakes each of them had at first.

| Before |
5 u - 16 |
1 u + 12 |
| Change |
+ 16 |
- 12 |
| After |
5 u |
1 u |
The number of mini cupcakes that Lily and Noah at first is the same.
5 u - 16 = 1 u + 12
5 u - 1 u = 12 + 16
4 u = 28
1 u = 28 ÷ 4 = 7
Number of mini cupcakes that each of them had at first
= 1 u + 12
= 7 + 12
= 19
Answer(s): 19
