Answer provided by our tutors
let
j = the number of card Jackie has
t = the number of card Tome has
k = the number of card Keri has
Jackie has five fewer cards than Tome:
j = t - 5
Keri has two more than triple the amount of cards Tom has:
k = 2 + 3t
the total number of cards all three of them have is 57:
j + k + t = 57
by solving the system of equations:
j = t - 5
k = 2 + 3t
j + k + t = 57
we find:
j = 7 card
k = 38 cards
t = 12 cards
