I'm trying to find the coordinates of a vector [ 7 4 1 ] relative to these three vectors:

[ -1 2 -9 ] , [ 1 5 1 ] , [ 47 -8 -7 ]

2. Relevant equations

none

3. The attempt at a solution

Do I get all these vectors into an augumented matrix?

like:

[ -1 1 47 | 7 ]

[ 2 5 -8 | 4 ]

[ -9 1 -7 | 1 ]

and then row reduce completely? I got very awkward numbers and just wanted to make sure I'm using the correct method.
