rezolvati problema la o ghereta se vindeau 427 kg de rosii,castraveti si ardei. afla ce cantitate de legume de fiecare fel era, daca rosii si castraveti erau in total 360 kg , iar ardei si castraveti in total erau 175 kg

Answer 1

r+c+a=427
r+c=360. r=360-c
a+c=175. a=175-c
r+c+a=427
360-c+c+175-c=427
360+175-c=427. c=108
r+c=360
r+108=360. r=252
a+c=175. a=67
