1. a - primul numar ; b - al doilea
    b = a + 2
    a + a + 2  = 66
    2a + 2 = 66
    2a = 66 - 2 = 64
    a = 32
    b = 32 + 2 = 34
 
2.  a - primul numar ; b -al doilea numar
     b = a + 2
     a + b = 84
     a + a + 2 = 84
     2a + 2 =  84
     2a = 84 - 2 =  82
      a =  41
      b = 41 + 2 = 43

1. Fie a,a+2 cele doua numere pare consecutive. a+a+2=66 --> 2a=64 --> a=32 --> a+2=34 2. Fie x,x+2 cele doua numere impare consecutive. x+x+2=84 --> 2x=82 --> x=41 --> x+2=43
