Notam cu a,b,c numerele
a+b+c=1000 a+b=584 b+c 601
din suma celor trei scadem suma ultimelor doua si ne ramane primul: a=(a+b+c)-(b+5) adica a=1000-601 a=399 ; acum scadem suma primelor doua si ne ramane ultimul c=(a+b+c)-(a+b) c=1000-584=416 si b=1000-399-416=185
a+b+c=1000
a+b=584 b+c=601 a+b+c+1000 584+c=1000 c=1000-584 c=416/b+c=601 /b+416=601 /b=601-416 /b=185/a+b=584/a+185=584/a=584-185/a=399
