This may seem like a very obvious question, but I thought it may be some sort of trick that my lecturer thought I may overlook... Well, when swapping columns of an augmented matrix, the solution set is unchanged (as long as you don't swap the 'b' column) is this correct? It is only swapping the way the matrix is set out (and would give you a different route to solve) but the solutions should not be altered in anyway.
