Question

Va rog rezolvati-mi si mie prin metoda segmentelor.
Mihai, Dan si Aurel au impreuna 238 de timbre. Cate timbre are fiecare, stiind ca daca Mihai ar avea 35, iar Dan i-ar da lui Aurel 47, toti ar avea acelasi numar de timbre.

Answer 1

M+D+A=238
M+35=D-47=A+47
M+35=D-47,D=M+35+47=M+82
M+35=A+47,A=M+35-47=M-12
M+M+82+M-12=238
3M=168
M=168:3=56
A=56-12=44
D=56+82=138
56+138+44=238

Sper ca te-am ajjjjjjjuat!
