hey there i have difficulty with augmented matrix ... can anybody  help me with that?

anonymous · Answer

sure, what's up?

anonymous · Answer

system:  x-4y+3z=5
            -x+3y- z=-3
             2x     -4z=6

anonymous · Answer

1 3 2   / 1
0 1 -2 /5

0  0  4  /4

anonymous · Answer

not is not a system

anonymous · Answer

coefficient matrix
1 -4 3
-1 3 -1
2 0 -4

anonymous · Answer

augmented matrix
1 -4 3 5
-1 3 -1 -3
2 0 -4 6

anonymous · Answer

is that the answer?

anonymous · Answer

no, that's an example, I'm not sure what your question is.  you just typed in a matrix.

anonymous · Answer

your augmented matrix is derived from the coefficients and constant terms of your system of linear equations

anonymous · Answer

is that the answer?

anonymous · Answer

do youwant me to write u the whole question maybe u gonna understant ??

anonymous · Answer

yes.  are you given a system of linear equations & asked to write an augmented matrix?

anonymous · Answer

find X, where x=(x1,x2,x3)to the power of t, given the A is known (3*) matrix, b a known column matrix, and that the system Ax=b has augmented matrix equivalent to

anonymous · Answer

1  3  2    ! -1
0  1 -2   ! 5
0  0  4    !  4

anonymous · Answer

thats is the qustion

anonymous · Answer

question sorry

anonymous · Answer

haha, yeah, sorry mattheos, that is a little more in depth than just having difficulty with an augmented matrix.  i'm in my first semester of linear algebra & i haven't seen a problem like that yet.

anonymous · Answer

aham ok ... thx anyway

anonymous · Answer

I'm going to repost your question if you don't mind, I would like to see a solution as well, I could solve this if it didn't involve the power of t.

anonymous · Answer

Do you have to use gaussian elimination?
