hello,

I really need someones help. Please give me a full explanation(not hints).thanks.

How do you Show that the system of equations Bx=b is consistent for all b is an element of R^3?

given that B=[1 2 0 1;1 0 1 -1;0 -1 3 -4] and Hence show that T spans R^3

T ={( 1 1 0),(2 0 -1),(0 1 3),(1 -1 4)}... please note that these are column vectors not row vectors.
