the ratio of the number of coins Azam had to the number of coins Eddie had was 3:7.Eddie gave 42 coins to Azam and they ended up having the same number of coins.how many coins did each person have at first? pls sh

orginal:
number of coins for Azam = 3x
number of coins for Eddie = 7x
Eddie gave 42 coins to Azam
Azam now has 3x + 42
Eddie now has 7x  42
but 7x  42 = 3x + 42
4x = 84
x = 21
So at first
Azam had 3(21) or 63
Eddie had 7(21) = 147
