Homework Statement
Using Gauss-Jordan elimination determine the intersection of the following systems. Identify the type of system geometrically.
a) 3x-2y+z=0
4x-5y+7z=0
6x+3y=0
b) x-2y+3z=0
x+y-z=4
2x-4y+6z=5
c) x+y+2z=-2
3x-y+4z=6
x+2y=-5
The Attempt at a Solution
I got the following intersections for the above systems.
a) (0,0,0)
b) (0,0,1)
c) (1,-3,0)
However, how do I "identify the system geometrically"? Also, how would identify the type of system and verify my solution using the normals of the planes?
I'm having a lot of trouble with this, if anyone could help me out I'd really appreciate it!
Thanks in advance!
