    Show that the range of the linear operator is not all of R^3

    Homework Statement Show that the range of the linear operator defined by the equations is not all of R3, and find a vector that is not in the range Homework Equations w1 = x - 2y + z w2 = 5x - y + 3z w3 = 4x + y + 2z The Attempt at a Solution can I just show that it does not have...
