notam,
X= nr trandafiri , y= numar garoafe , Z= nr irisi
X+Y+Z= 206
X=Z+16 => Z=X-16
Y=3*Z => Y= 3(x-16)
Acum inlocuim in prima ecuatie Y-ul si Z-ul care le-am scris in functie de X.
X+ 3(X-16) +x-16=206
X+3x-48+x -16=206
5x= 48+16+206
5x=270
x=54 (trandafiri)
Z(irisi) = 54-16= 38
Y(garoafe)= 38*3 = 114
Verificare:
54+38+114=206
