A=nr de timbre pe care le are primul copil

B=nr de timbre pe care le are al 2 copil

A+B=94

A=7B

-------------------------------------------------

A)A,B=?

------------------------------------------------------

Inlocuim, A cu 7b din relatia A+B =) 7B+B=94 =) 8B=94=)B=11.75

A=7xB si stim B si inlocuim 7x11.75=82.25

                                                                                Deci dai raspunsu asa:A=82 de timbre

                                                                                                                      B=11 timbre
