I rent out 3 room in my primary residents and earn a rental income. Do i file schedule E only for my property and rental income or do i file schedule A and E together?

am i allowed to file both together while submitting both mortgage interest, pmi, property taxes, on each schedule form or separately, or am i suppose to select one schedule form to file? probably schedule e? only?
