Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
¿Por qué Diego hizo eso? ¿Cómo le ayudó eso a encontrar el valor de que hace que la ecuación sea verdadera?
¿Cómo podría Diego justificar cada movida?
Esta es una ecuación y la solución. ¿Qué movidas podrías hacer para ir de la ecuación a la solución? Justifica cada movida que hagas:
