Question

4KG DE MERE SI 3 KG DE CAPSUNE COSTA 32 DE LEI DOUA KG DE MERE SI 5 KG DE CAPSUNE COSTA 38,40 LEI CAT COSTA UNN KG DE MERE SI UNU DE CAPSUNE

Answer 1

4m+3c=32, 3c=32-4m, c=(32-4m)/3
2m+5c=38,4, 2m+5(32-4m)/3=38,4, 2m+(160-20m)/3=38,4
6m+160-20m=115,2
14m=160-115,2=44,8, m=44,8/14=3,2 lei
c=(32-4m)/3=(32-4*3,2)/3=(32-12,8)/3= 19,2/3=6,4 lei

Answer 2

4M +3 C =32
2M+5C =38.4 l *2

4M+3C=32
4M+10C =76.8  l -
----------------------------
  /     7C =44.8
C =6.4 lei

4M+3C =32
4M +3*6.4 =32
4M +19.2 =32
4M =32-19.2 =12.8
M =3.2 lei
