Răspuns :
Fie r - nr. trandafiri rosii, g - nr trandafiri galbeni.
r=3g
g+40=r
Deci, g+40=3g \ -g (Scadem "g")
40=2g
g=20
r=3*20
r=60
Total : r+g=60+20=80 trandafiri
r=3g
g+40=r
Deci, g+40=3g \ -g (Scadem "g")
40=2g
g=20
r=3*20
r=60
Total : r+g=60+20=80 trandafiri
r = 3g
r = g + 40
3g = g + 40
2g = 40
g = 40 : 2
g = 20 trandafiri galbeni
r = 3 * 20
r = 60 trandafiri rosii
20 + 60 = 80 trandafiri in total
20 + 40 = 60 trandafiri galbeni
r = g + 40
3g = g + 40
2g = 40
g = 40 : 2
g = 20 trandafiri galbeni
r = 3 * 20
r = 60 trandafiri rosii
20 + 60 = 80 trandafiri in total
20 + 40 = 60 trandafiri galbeni
