Explicación paso a paso:
no dice que son numero menores a 12 ( < 12):
*Solo reemplazamos la "X"
3x - 9 < 12
3(6) - 9 = 9
3(5) - 9 = 6
3(4) - 9 = 3
3(3) - 9 = 0
3(2) - 9 = -3
3(1) - 0 = -6
3(0) - 9 = -9
----------------------------------------------
entonces: B = [-9; -6; -3; 0; 3; 6; 9]
------------------------------------------------
si solo usas numeros naturales:
=> B = [0; 3; 6; 9]
