George and Emma had the same number of lollipops. After Emma gave away 20 lollipops and George gave away 39 lollipops, Emma had 2 times as many lollipops as George. How many lollipops did each of them have at first?
| |
George |
Emma |
| Before |
1 u + 39 |
2 u + 20 |
| Change |
- 39 |
- 20 |
| After |
1 u |
2 u |
The number of lollipops that George and Emma had at first is the same.
2 u + 20 = 1 u + 39
2 u - 1 u = 39 - 20
1 u = 19
1 u = 19 ÷ 1 = 19
Number of lollipops that each of them had at first
= 1 u + 39
= 19 + 39
= 58
Answer(s): 58
