Answer 1

e=3o( aici e o nu 0)
s=3o
287 mere
Cate mere are fiecare
e-Ene
o-Oana
s-Sorana

3o+3o+o=287
7o=287
o=287/7= 41 mere are Oana

Ene are 41*3=123
Sorana are 41*3=123

123+123+41=287 mere

Answer 2

E = 3 OANA
S = 3 OANA
E + S + O = 287
3 OANA + 3 OANA + OANA = 287
7 OANA = 287
OANA = 287 : 7
OANA = 41 mere
ENE = 3 * 41
ENE = 123 mere
SORANA = 3 * 41
SORANA = 123 mere
Proba: 123 + 123 + 41 = 287 mere
