11
Step-by-step explanation:
1.Como primer paso debemos realizar la distributiva para destruir ese paréntesis :
11x-55=66
2. Después procedemos a dejar la variable a despejar en lado izquierdo del igual y las constantes al lado derecho :
11x=55+66
11x=110
3. Por ultimo procedemos a despejar esa x que esta acompañada de una constante de tal forma la constante que esta multiplicando pasara a dividir con la otra constante :
x=110/11
x=11
De tal manera la respuesta es aceptable ya que 11 se encuentra dentro del conjunto {6, 7, 11}
Otra manera es sustituir el 6,7,11 para saber cual cumple la ecuación
x=6
11(6-5)=?66
11(1)=11>Esto es incorrecto 11 No es igual a 66
x=7
11(7-5)=?66
11(2)=22>Esto es incorrecto 22 No es igual a 66
x=11
11(11-5)=?66
11(6)=66>Esto es correcto 66 Si es igual a 66
