Norman · Answer 1

L + F + G = 51

F = 3L ... F = 3 (G + 4) ... F = 3G + 12

L = G + 4

(G + 4) + (3G + 12) + G = 51

5G + 16 = 51

5G = 51 - 16

5G = 35

G = 35/5

G = 7 < = = = Greg sold 7

L = G + 4 ... L = 7 + 4 ... L = 11 < = = Lin sold 11

F = 3G + 12 ... F = 3 (7) + 21 ... F = 21 + 12 ... F = 33 < = = Fran sold 33
