Bryan and Xuan had the same number of sweets. After Xuan gave away 19 sweets and Bryan gave away 43 sweets, Xuan had 3 times as many sweets as Bryan. How many sweets did each of them have at first?
| |
Bryan |
Xuan |
| Before |
1 u + 43 |
3 u + 19 |
| Change |
- 43 |
- 19 |
| After |
1 u |
3 u |
The number of sweets that Bryan and Xuan had at first is the same.
3 u + 19 = 1 u + 43
3 u - 1 u = 43 - 19
2 u = 24
1 u = 24 ÷ 2 = 12
Number of sweets that each of them had at first
= 1 u + 43
= 12 + 43
= 55
Answer(s): 55
