Formulate but Do Not Solve the Problem

Formulate but do not solve the problem. Cantwell Associates, a real estate devloper, is planning to build a new apartment complex consisting of one bedroom units and two- and three- bedroom townhouses. A total of units is planned, and the number of family units (two- and three-bedroom townhouses) will equal the number of one-bedroom units. If the number of one-bedroom units will be times the number of three-bedroom units, find how many units of each type will be in the complex. Let x be the number of one-bedroom units, y be the number of two-bedroom units, and z be the number of three-bedroom units.
