help me solve matrices

  • math -

    I hope your other one didn't need matrices because..I did it the other way.


    4 -1 -3 8
    2 2 -1 3
    6 1 -3 2

    You want to manipulate the rows so that in the end, you end up with

    1 0 0 a where a = the value for x
    0 1 0 b where b = the value for y
    0 0 1 c where c = the value for z.
