Question

Suma a doua numere este 18.Daca din suma scadem diferenta celor doua numere,obtinem 16.Care sunt cele doua numere?

Answer 1

a+b=18

18-(a-b)=16

a-b=18-16->a-b=2->a=b+2                      b+b+2=18

                                                                2b=18-2

                                                                2b=16

                                                                b=16:2

                                                               b=8->a=8+2

                                                                        a=10
