to help him, to help her, to help you (formal)
Me alegra haber podido ayudarle la semana pasada.
I'm glad I was able to help you last week.
Ella hizo todo lo que pudo para ayudarle.
She did everything she could to help him.
Le di la mano intentando ayudarle.
I shook his hand, trying to help him.
We’re sorry we can’t help you.
Prometí a mi hermano ayudarle con su tarea.
I promised my brother I would help him with his homework.
