Question

impartind doua nr naturale,obtinem catul14 si restul3.daca impartim suma lor la diferenta lor,obtinem catul 1 si restul 26.aflati numerele

Answer 1

a:b=14 rest 3, a=14b+3
(a+b):(a-b)=1 rest 26
(a+b)=(a-b)+26

14b+3+b=14b+3-b+26
14b+b-14b+b=3+26-3
2b=26
b=13

a:13=14 rest 3, a=13*14+3, a=185
