A + b + c = 23 320
a + b = 13 746
b + c = 3 660 + 13746
a = 13746 - b
c = 17406 - b
13 746 - b + b + 17 406 - b = 23 320
- b = 23 320 - 31 152
b = 7 832
c = 17 406 - 7 832
c = 9 574
a = 13 746 - 7 832
a = 5 914

 Numerele necunoscute le notam cu a,b,c.
 a+b+c= 23.320; a+b= 13.746;
 b+c= 3.660+13.746.
a= 13.746 -b; c= 17.406-b;
13746- b+b+ 17.406 -b = 23320 -b=
31 152- 23 320 =>> b= 7832..
 a= 13 746 -7 832 ; a= 5914
c= 17 406- 7832.. c= 9574. Bafta :) :)
