Răspuns :
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
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
