Hi,

A total of 168 units is planned, and the number of family units (2 and 3-bedroom townhouses) will equal the number of one-bedroom units. 

If the number of one-bedroom units will be 3 times the number of three-bedroom units

one-bedroom units:  units        or 84 Units

two-bedroom townhouses units    or 56 Units

three-bedroom townhouses   units  or 28 Units

     6x = 168,  x = 28
