Anne has 24 more cards than devi. anne finds that 3/5 of devi's cards are equal to 1/2 of her cards. how many cards does anne have?

Anne = x

devi = y

x = y + 24

1/2 x = 3/5 y

x = 6/5 y (we devided both by 1/2)

6/5 y = y + 24

6/5 y - y = 24

1/5 y = 24

y = 24 * 5 = 120

x = 120 + 24 = 144

so anne has 144 cards and devi has 120 cards.
