Answer 1

5) o+g+s=4680kg.cereale
    o+g=3800kg
    g+s=2900kg
------------------------------------
   o=?kg.; g=?kg.;s=?kg

3800+s=4680kg
s=4680-3800
s=880kg. (secara)

o+2900=4680kg.
o=4680-2900
o=1780kg. (orz)

1780+g+880=4680kg
g=4680-(1780+880)
g=4680-2660
g=2020kg. (grau)

1780+2020+880=
=3800+880
=4680kg.cereale

6)    (19+13)*2=
      =32*2

Answer 2

1)o+g+s=4680
o+g=3800
g+s=2900
3800+s=4680
s=4680-3800
s=880 kg secară
o+2900=4680
o=4680-2900
o=1780 kg orz
g=4680-880-1780
g=2020 kg grâu

2)19+13=jumătate=>jumătate=32
