Răspuns :
a +b + c = 237
26+35+38 = 99
237-99 = 138
138 : 3 = 46 cantitatea egala
46+26 = 72 kg
46+ 35 = 81 kg
46+ 38 = 84 kg
26+35+38 = 99
237-99 = 138
138 : 3 = 46 cantitatea egala
46+26 = 72 kg
46+ 35 = 81 kg
46+ 38 = 84 kg
a+b+c=237
x-cantitatea de cartofi vanduta
a-x=26⇒ a=26+x
b-x=35⇒ b=35+x
c-x=38⇒ c=38+x
26+x+35+x+38+x=237
99+3x=237
3x=237-99
3x=138
x=138/3
x=46 kg cantitatea de cartofi vanduta din fiecare sac
cate kg au fost in I sac?
a=26+x
a=26+46
a=72
in al II sac: b=35+46⇒b=81kg
in III sac: c=38+46⇒c=84kg
verificare
72+81+84=237
