Question

a+b=28 b+c=46 a+c=40 aflati a , b si c

Answer 1

A+b+b+c+a+c=28+46+40
2a+2b+2c=114
2x(a+b+c)=114
a+b+c=114:2
a+b+c=57
28+c=57
c=57-28
c=29
a+46=57
a=57-46
a=11
b+40=57
b=57-40
b=17

Answer 2

a+b=28 b+c=46 a+c=40 a+b+b+c+a+c= 28+46+40=>28+86=>114 a+b+c=114:2 a+b+c=56 a+b=28 c=56-28 c=28 b=46-28 b=18 a=28-18 a=10 R:a=10 b=18 c=28
