Brazi |__|__|__| Pini   |__|                }146 Fagi  |__|__|__|+6 146-6=140(am egalat segmentele) 140:7=20 reprezintă un segment Brazi:20×3=60 Pini:20 Fagi:(20×3)+6=66

146 arbori

b = 3 × p

f = b + 6

b + p + f = 146

_____________________

b , f , a = ?


p  /-------/

b  /-------/-------/-------/                suma 146

f  /-------/-------/-------/-6-/


146 - 6 = 140

140/7 = 20 ( valoarea unui segment )

20 - pini

20 × 3 = 60 brazi

60 + 6 = 66 fagi
