Fie a,b,c - cele 3 numere
a+b+c\3=22⇒a+b+c=66
a+b\2=28⇒a+b=56
b=a:6⇒a=6b
6b+b=56
7b=56
b=8
a+8=56
a=48
48+8+c=66
56+c=66
c=10

stiim ca : (a+b+c):3 =22 => a+b+c = 66 ;
(a+b) : 2 = 28 adica: a+b = 56 , unde a = 6b
↓
6b+b =56 deci b=8 iar a=48.

8+48+c =66
c = 10.
(a+b) : 2 = 28 adica: a+b = 56 , unde a = 6b
