1)
Trei carti au inpreuna 366 de pagini.Prima carte are de 2 ori mai multe pagini decat a doua,iar a treia de 3 ori mai multe decat a doua.
Cate pagini are fiecare carte?

2)
In doi saci sunt 150 kg de faina.Daca din primul sac se scot 3 kg si se adauga la al doilea , atunci in primul sunte de doua ori mai multe kg decat in al doilea.
Cate kg de faina sunt in fiecare sac?

Aflati numerele stiind ca primul numar este de 5 ori mai mare decat al doilea.

Aceste exercitii sunt atat de usoare incat propun sa le faci singur.

c=3b
2b+b+3b=366=>6b=366=>b=61
a=122 si c=183

3) a-b=800
a=5b
5b-b=800=>b=800:4=>b=200
