Answer 1

Vlad are --- x timbre
Andrian are --- 3x timbre                 in total 670 timbre
Bogdan are --- 4x timbre
Daniel are --- 2x timbre
Se obtine ecuatia: x+3x+4x+2x=670,  10x=670,  x=67 timbre (Vlad)
3·67=201 timbre ( Andrian)
4·67=268 timbre (Bogdan)
2·67=134 timbre (Daniel)
Verificare: 67+201+268+134=670
Raspuns: Vlad are 67 timbre, Andrian are 201 timbre, Bogdan are 268 timbre, Daniel are 134 timbre
