Question 514509
Cantwell Associates, a real estate developer, is planning to build a new apartment complex consisting of x one-bedroom units, y two-bedroom townhouses, and z three-bedroom townhouses. 
--------------------------------------
A total of 192 units are 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 3 times the number of three-bedroom units, find how many units of each type will be in the complex.
----------------
x + y + z = 192 units
y+z = x
x = 3z
----
Rearrange:
x + y + z = 192
x - y - z = 0
x + 0 -3z = 0
