435:2=217,5 ≈218 trandafiri albi
218+24=242 trandafiri rosii

Multumesc

x= trandafiri rosi si albi
x1= trandafiri rosii si x2=trandafri albi, x=x1+x2 x1=x2 supra 2+24 x=x2 supra 2 + 24+ x2 435-24=x2+2x2 supra 2 411ori 2= 3ori x2 822=3ori x2 x2=274 x1=161

a+b =435

a=24+b :2

24+b:2+b=435,se inmulteste cu 2

48+b+2b=870

3b=822

b=274

⇒ a=435-274=161
