Răspuns :
1zi.........x kg de struguri
2zi..........4x+10 kg de struguri in total:2510kg de struguri
3zi..........0,5x-8 kg de struguri
Rezolvare:
1)alcatuim o ecuatie
x+4x+10+0,5x-8=2510(kg)
5,5x=2510-10+8
5,5x=2508
x=2508 : 5,5
x=456(kg in pima zi)
2)aflam cite kg de struguri familia a strins in a 2 zi
4*456+10=1834(kg)
3)aflam cite kg de struguri familia a strins in a 3 zi
0,5*456-8=220(kg)
Raspuns: 1zi---456kg
2zi---1834kg
3zi---220kg

a+b+c = 2510
b=4a+10
c= a/2 -8
a+4a+10+a/2-8 = 2510
5a+a/2+ 2= 2510
11a/2 = 2508
