DAU COROANA!URGENTTT!!

Answer 1

b1=primul butoi
b2=al doilea butoi
b3=al treilea butoi
x=cantitatea de vin consumata
a+b+c=58dal=580 l
a-x=113 l
b-x=630dl=63 l
c-x=14300cl= 143 l
(a-x)+(b-x)+(c-x)= 113 l + 63 l + 143 l= 319 l
3x= (a+b+c) - [(a-x)+(b-x)+(c-x)]= 580 l - 319 l
3x= 261l
x= 261 : 3 = 87 l

a-x= 113l, a-87 l = 113 l => a= 113+87= 200l
b-x= 63l, b-87 l = 63 l => b= 63+87= 150l
c-x= 143l, c-87 l = 143l => c= 143+ 87 = 230

Verificare:
200+150+230= 580 l
