Question 149628
Solve the system: 
x-y-z=1
-x-y+2z=-2
-x-3y+z=-5

Using determinants:
X	Y	Z	
			
1	-1	-1	 1
-1	-1	2	-2
-1	-3	1	-5


Det = 	4
	
X =	3
Y =	1
Z =	1

Other methods can be used, but I have an Excel sheet that does these using determinants. If you want another method, or more info on the Excel sheet, email me at gsihoutx@aol.com
