    equations. We can proceed in a similar way in general. Given a system Ax = b we construct a matrix T by adding to A an extra column corresponding to b, i.e. T = (A|b). Let T = (A |b ) be A = YA and b = Y b. So, in particular, Ax = b and A x = b have the same set of solutions. We say that T is the...
