Răspuns :
( a + b + c ) : 3 = 14, 8
a = 2, 45
a + b + c = 14, 8 × 3
a + b + c = 44, 4
2, 45 + b + c = 44, 4
b + c = 44, 4 - 2, 45
b + c = 41, 95 => suma celorlalte numere
a = 2, 45
a + b + c = 14, 8 × 3
a + b + c = 44, 4
2, 45 + b + c = 44, 4
b + c = 44, 4 - 2, 45
b + c = 41, 95 => suma celorlalte numere
