For the matrix A below: Without doing any computation, first explain why the columns of A have to be linearly dependent, and then why the equation Ax = 0 has infinitely many solutions. Having done that, delete as few columns as possible from A to depict a matrix B for which the equation Bx = 0 has only the trivial solution
