Question 836406
:
Please help with this equation:
2x+z+3w=0
-x+2y-z-2w=2
x-y+w=2
I did this:
2 0 1 3|0
-1 2 -1 -2|2
1-1 0 1|2
2 0 1 3|0
1 0 -1 0|6
1 -1 0 1|2
2 0 1 3|0
1 0 -1 0|6
0 0 1 1|-4
2 0 0 2|-4
1 0 -1 0|6
0 0 1 1|-4
2x+2w=-4
x-z=6
z+w=-4
and got stuck there. Am I even on the right track here?
