The number of 3X3 matrices whose entries are either 1 or 0 and for which the system [ x ] [1]A [ y ] = [0] has exactly two distinct [ z ] [0] solution is :a) 0b) 2^9 - 1c) 168d) 2***NOTE: I tried my best to make it look like a 3 X 1 matrix, just remember they [x y z] and [1 0 0] are botb 3 X 1 matrices (vertically align than what I have shown)***Also Answer is 0 but how ???
