d-descazutul
s-scazatorul
d-s=978
s=978+1024=2002
d=978+s
d=978+2002=2980

5.a,b,c-nr nec
a+b+c=23092
a+b=15109
15109+c=23092
c=23092-15109
c=7983
b+c=16707
b=16707-7983
b=8724
a+8724=15109
a=15109-8724
a=6385

Answer 2

3) 

a-b=978
b=r+1024
------------
a=?

b=978+1024
b=2002

a=2002+978
a=2980

a-b=978
2980-2002=978

5)

a+b+c=23092
a+b=15109
b+c=16707
-------------------
a=?;b=?;c=?

a+b+c=23092
a+b=15109

23092-15109=7983
c=7983

b+c=16707
23092-16707=6385
a=6385

23092-(a+c)=b
b=23092-(6385+7983)
b=23092-14368
b=8724

a+b+c=23092
6385+8724+7983=23092
