THE SEWAGE IS BACKING UP A DRAIN PIPE IN THE HOUSE WHEN WE DO LAUNDRY OR TAKE A SHOWER AND THE WATER BARELY MOVES WHEN WE FLUSH THE TOILET. HOW DO WE REMEDY THIS PROBLEM?

Once you get to a point where the water is backing up in multiple fixtures it means either the main sewer line from the house to the city sewer or septic tank has a blockage. Once these lines get filled, a small hand snake is ineffective. The same with chemical clog removers. You’re way past that point. Right now you are at the stage where you need a professional to solve your sewer problems.
