10 lazi cu visine si 12 lazi cu cirese au cantarit 277 kg. Cate kg de visine erau intr-o lada? dar de cirese?​

Răspuns :

10 lazi visine..........12 lazi cirese..........188 kg /x2
20 lazi visine..........13 lazi cirese..........277 kg
---------------------------------------------------------------------
20 lazi visine..........24 lazi cirese..........376 kg
20 lazi visine..........13 lazi cirese..........277 kg
------------------------------------------------------------------
// 11 lazi cirese..........99 kg
1 lada cirese=99:11
1 lada cirese=9 kg

20 lazi visine+13x9=277
20 lazi visine+117=277
20lazi visine=160 kg
1 lasa visine=8 kg

proba: 8x20+13x9=160+117=277
