Răspuns:
A = Alin, S = Sabin, C = Claudiu
a + s + c = 38
a = s + 6
c = s + 5
Inlocuim
s + 6 + s + s + 5 = 38
3s + 11 = 38
3s = 38 - 11
3s = 27
s = 9
Daca s = 9 => a = s + 6 = 9 + 6 = 15
si c = s + 5 = 9 + 5 = 14
Verificare
a + s + c = 38
9 + 15 + 14 = 38 Adevarat
Concluzie Sabin 9 poze, Alin 15 poze si Claudiu 14 poze
