Kaya and Tad started with the same number of baseball cards in their collections. Kaya collected 3 cards per week and now has 29 cards. Tad collected 2 cards per week and now has 20 cards. Let x represent the number of cards they began with, and let y represent the number of weeks. Which system of equations represents this situation?

x + y = 20

3x + 2y = 29

5y = 49

x + 20 = 29

x + 3y = 20

x + 2y = 29

x + 3y = 29

x + 2y = 20
