How many cards does Tommy give to each friend if he gives out a total of 74 cards?

Question

Tommy gives baseball cards to four of his friends.

He gives Kiana 3 cards less than he gives Gary. He

gives Monty 7 cards more than he gives Kiana. He 

gives Willa twice as many as he gives Monty. How 

many cards does Tommy give to each friend if he gives

out a total of 74 cards?

Answer 1

K = G-3

M = K+7 = G-3+7 = G+4

W = 2M = 2G + 8

G-3 + G+4 + 2g+8 + g = 74

5g + 9 = 74

5g = 65

g = 13

Gary gets 13

Kiana gets 10

Monty gets 17

Willa gets 34
