Explanation:

The most important thing when transforming reported to indirect speech is the tense shift. We shift to "a backward tense" (Present Simple to Past Simple, Past Simple/Present Perfect to Past Perfect, will to would, can to could etc.)

Also the verb changes depending on the context of the sentence (an order, suggestion, proposal, information etc.)

Note the change in possesive and personal pronouns.
