Observam ca toate segmentele sunt egale. Trebuie sa aflam cat inseamna un segment
5xn+20=170
5xn=170-20
5xn=150
n=150:5
n=30
z=n+n+n
z=30+30+30
z=90
b=n+20
b=30+20
b=50
=======================================================
n+b+z=170
z=3n
b=20+n
Inlocuim in prima expresie
n+20+n+3n=170
5n=170-20
5n=150
n=150:5
n=30 (Nina a vizitat 30 de flori)
z=3x30
z=90 (Zina a vizitat 90 de flori)
b=20+30
b=50 (Bina a vizitat 50 de flori)
