Xylia and Raeann had the same number of cards. After Xylia had given away 72 cards, Raeann had 5 times as many cards as Xylia. How many cards did each of them have at first?
| |
Xylia |
Raeann |
| Before |
1 u + 72 |
5 u |
| Change |
- 72 |
|
| After |
1 u |
5 u |
Number of cards that Raeann had remains unchanged.
Number of cards that Xylia and Raeann had at first is equal.
5 u = 1 u + 72
5 u - 1 u = 72
4 u = 72
1 u = 72 ÷ 4= 18
Number of cards that each of them had at first
= 1 u + 72
= 18 + 72
= 90
Answer(s): 90
