Explanation:
Changing a speech from the direct to indirect speech involves the change in the way the speech is reported and also the verb tenses are also changed accordingly. Moreover, the pronouns are also changed and also certain phrases are also changed to their corresponding forms.
This means that if the verb is in the present tense in the direct speech, then it will be changed to the past tense in the reported form. Also, words or phrases such as "tomorrow" will be changed to "the next day", "yesterday" to "the previous day", etc.
The given direct speeches are changed to the indirect form as follows-
