Explicație pas cu pas:
6.a+b+c=976000
a-|----|=86000
b-|----|=160000
c-|----|=340000
a |----|+86000
b |----|+160000
c |----|+340000
976000-(86000+160000+340000)=
976000-(246000+340000)=
976000-586000=390000(3 |----| egale)
390000:3=130000(1 |----|)
130000+86000=216000( a)
130000+160000=290000( b)
130000+340000=470000( c)
7.3 ciobani au impreuna 976000 vaci . daca de la fiecare pleaca acelasi numar de vaci ei raman cu 86 000, 160 000, 340 000. cate vaci a avut la inceput fiecare cioban?
