Ront si Puf au impreuna 836 alune. Daca Ront ii da 30 de alune vor avea acelasi numar de alune. Cate alune are fiecare?

Răspuns :

[tex]r+p=836 \\ r-30=p+30=\ \textgreater \ r=p+30+30=\ \textgreater \ r=p+60 \\ p+60+p=836 \\ 2p=836-60 \\ p=776:2 \\ p=388 alune.are.Puf \\ r=388+60=448 .alune.are.Ron[/tex]
