    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Please give step by step instructions and name each step like triangular form, augmented matrix etc so I know when and what to do and can understand it. We are not using calculator so the steps need to be shown to the solution.

    1) Compute u + v and u - 2v

    u = -1 ; v = -3
    2 -1

    2) Display the following vectors using arows on an xy graph: u, v, -v, -2v, u+v, u-v, and u-2v. Use u and v from #1.

    3) Write a system of equations that is = to the given vector equation.

    6 -3 1
    xsub1 -1 + xsub2 4 = -7
    5 0 -5

    4) Write a vector equation that is equivalent to the given system of equations.

    xsub2 + 5xsub3 =0
    4xsub1 + 6xsub2 - xsub3 = 0
    -xsub1 + 3xsub2 - 8xsub3 = 0
