In trei camioane s-au incarcat 31 tone de lemne. In primele doua camioane, s-au incarcat 160 chintale.iar in ultimele doua, 240 chintale. Cate kilograme de lemne s-au incarcat in fiecare camion ? dau coroana si 72 de puncte !
10 q = 1 tona 160 q = 16 tone 240 q = 24 tone a = I camion b = II camion c = III camion a + b = 16 c + b = 24 a + 2b+ c = 16+24 = 40 a +b + c = 31 2b- b = 40 - 31 b = 9 tone = 9000 kg a = 16 - 9 = 7 tone = 7000 kg c = 24 - 9 = 15 tone = 15000 kg
16000+c=31000=>c=31000-16000=>c=15000 kg lemne al3lea camion a+24000=31000=>a=31000-24000=>a=7000 kg lemne in primul camion 7000+b=16000=>b=16000-7000=>.b=9000 kg al2lea camion
