Calculezi a+b+a+c+b+c=148+120+132
2a+2b+2c=400/:2
a+b+c=200
c=200-148=52
a=120-52=68
b=148-68=80
multumesc frumos
Toate sumele adunate dau 2a+2b+2c=400,
deci a+b+c=400/2 adica 200 si acm este foarte simplu din 200 scazi fiecare suma si afli cate un termen
c=200-148=54
a=120-52=68
iar b =132-52=80

a+b   =148
a    +c=120
    b+c=132
a+a+b+b+c+c=400
a+b+c=200
200-148=52(c)
200-120=80(b)
200-52-80=68
