After these verbs you can use to ... (infinitive):

• Simon was in a difficult situation, so I agreed to help him.
• How old were you when you learnt to drive? (or learnt how to drive)
• I waved to Karen, but failed to attract her attention.

After some verbs to ... is not possible. For example, enjoy/think/suggest:
• I enjoy reading. (not enjoy to read)
• Tom suggested going to the cinema. (not suggested to go)
• Are you thinking of buying a car? (not thinking to buy)
