Landlord questions about tenants?

Hi I am a new landlord, decided to rent my house out to a older lady and her daughter. After they were in for 2 weeks she asked if her friend could move in to help with the rent. I agreed to this but told her she needed to be put on the lease. I didn't hear anything back, then a couple weeks later I went over to the house, was talking to the neighbor. The Neighbor proceeded to inform me the not only their was the new lady but there was another big dog, a man living with them. I don't feel comfortable with this situation as all has been a lie. Now the lady I originally rented to wants them gone but don't want the drama that it will cause. I need to know what I can do as a landlord. I would like them all out and start over. The rent was not paid yet but she has until the 5th to pay. Please help I live in Michigan if this helps Thanks for your time Joe...
