Ferma animale
La o ferma sunt 40 de vaci cu 30 de vitei si 80 de oi cu 40 de miei care consuma zilnic 1200 kg furaje. O vaca mananca cat 3 vitei, iar un miel jumatate din cantitatea consumata de o oaie. Cate kg furaje mananca fiecare animal daca 20 de vaci si 20 de oi consuma 360 de kg ?

Notam :
- vacile : v
- viteii : v2
- oile : o
- mieii : m
REZOLVARE
40v + 30v2 + 80o + 40m = 1200 kg furaje
40v + 10 v + 80o+20o= 1200 kg furaje
50 v +100o = 1200 kg furaje
20 v + 20o= 360 kg furaje / : 20
1v+ 1o = 18 kg furaje
50 ( 18 kg furaje - 1o ) + 100o = 1200 kg furaje
900 kg furaje - 50o +100o = 1200 kg furaje / - 900 kg furaje
50o = 300 kg furaje
1o = 6 kg furaje
1v = 12 kg furaje
1m = 3 kg
1v2 = 4 kg
