If you were to use gauss-jordan elimination on the following linear system, what would the augmented matrix be?
3w − x = 2y + z − 4
9x − y + z = 10
4w + 3y − z = 7
12x + 17 = 2y − z + 6

Awe yiss, gauss-jordan elimination
well, you would have to get it into form
ax+bx+cy+dz=e where a,b,c,d,e are constants

then just take their coefients
so

get into  that form

3w-1x-2y-1z=-4
0w+9x-1y+1z=10
4w+0x+3y-1z=7
0w+12x-2y+1z=-11

depending on if you put w first or last (I would put it first before x) if you put w first it would look like this


A is the answer

Im pretty sure it’s the first one
