Valen and Seth had a total of 159 cards at first. After Valen bought 22 more cards and Seth gave away 13 cards, Valen now has the same number of cards as Seth. How many cards did Valen have at first?

Valen |
Seth |
Total |
| Before |
1 u - 22 |
1 u + 13 |
159 |
| Change |
+ 22 |
- 13 |
|
| After |
1 u |
1 u |
168 |
Total number of cards in the end
= 159 + 22 - 13
= 168
2 u = 168
1 u = 168 ÷ 2 = 84
Number of cards that Valen had in the end
= 1 u
= 84
Number of cards that Valen had at first
= 84 - 22
= 62
Answer(s): 62
