yeah, if i take my basis for the ker(A) and plug the vaules back into the original system i get all of the equations to equal zero. is that right then?
thanks for the help by the way :)
I'm not sure what " maps to the zero vector" means, this is my first course in Linear Algerbra ( two class periods so far ) and we don't have a book to work from.
After I reduce the matrix A|B I get
1 0 0 -1 | 0
0 1 0 1 | 2
0 0 1 0 | 1
which gives
x -w...
