Answer 1

x=rosii
y=castraveti
z=ardeii

x+y+z=427kg=>x+175=427=>x=427-175=>x=252kg rosii
x+y=360kg=>252+y=360=>y=360-252=>y=108kg castraveti
y+z=175kg=>108+z=175=>z=175-108=>x=67kg ardei

V: 252+108+67=427kg legume

Answer 2

am notat:
r-rosii
c-castraveti
a-ardei

r+c+a=427 kg
r+c=360 kg
r=360-c
a+c=175 kg
a=175-c
360-c+c+175-c=427
360+175-c=427
535-c=427
c=535-427
c=108
r=360-108
r=252
a=175-108
a=67
verificare
252+108+67=427 kg
Sper ca te-am ajutat!
