Răspuns :
Notam:
a = numarul trandafirilor albi
r = numarul trandafirilor rosii
a + r = 57
a |______|
r |______|+3
57 - 3 = 54
54 : 2 = 27 (un segment egal)
a = 27 trandafiri albi
r = 27 + 3 = 30 trandafiri rosii
Verificare:
27 + 30 = 57
a = numarul trandafirilor albi
r = numarul trandafirilor rosii
a + r = 57
a |______|
r |______|+3
57 - 3 = 54
54 : 2 = 27 (un segment egal)
a = 27 trandafiri albi
r = 27 + 3 = 30 trandafiri rosii
Verificare:
27 + 30 = 57

57-3=54 (2 segmente egale)
54:2=27 (1 segment)
r=27+3=30
