Julie and Zoe had an equal number of lollipops. After Julie bought another 22 lollipops and Zoe bought another 4 lollipops, Julie had four times as many lollipops as Zoe. Find the number of lollipops that each of them had at first.

| Before |
4 u - 22 |
1 u - 4 |
| Change |
+ 22 |
+ 4 |
| After |
4 u |
1 u |
The number of lollipops that Julie and Zoe had at first is the same.
4 u - 22 = 1 u - 4
4 u - 1 u = 22 - 4
3 u = 18
1 u = 18 ÷ 3 = 6
Number of lollipops that each had at first
= 6 - 4
= 2
Answer(s): 2
