... We can multiply the vector x to CA = CAx = x which can be rewritten as CAx = x because x was being multiplied by an identity matrix. Since Ax= 0 we can substitute that in x = CAx and get C0 = 0 which shows that it has only the trivial solution. This also shows us that A is linearly independent becau ...
