  • Could u make a more complicated problem maybe involving 4 variables?

  • I could but I am teaching 6 classes right now and don't really have time.

    Just make an x column, y column, z column, and w column and then the constants.

    Then follow the example.

  • For A is invertible, Ax = b has augmented matrix...

    (A,b) = (A, Ax) = A(I,x).

    Multiplying from left by E, a product of elementary matrices gives..

    EA(I,x) = I(I,x) = (I,x)

  • This video helped me pass this chapter in my class. Thank you

  • Thank you. It`s really need me!

  • Thank You sooooooo much!!

  • I've never heard of any college professor say minus 17 or minus 3. It's customary to say negative 17 or negative 3.

  • Thumbs up if Thinkwell brought you here!

  • I think I love you! We'll see how I do on my online quiz... :P

  • Thank You very much! Your explanation was simple and painless!! I get it now!!
