how would i use
elementary row operations to apply gauss jordan process to solve these systems of linear eqns.

3.x-z=- 2x + y-3z = 5 ( x+2y + 2z = 4 54 2 32 yy x+2 3x 2x

Solution

Your matrix

Find the pivot in the 1st column and swap the 3rd and the 1st rows

Eliminate the 1st column

Make the pivot in the 2nd column by dividing the 2nd row by -3

Eliminate the 2nd column

Make the pivot in the 3rd column by dividing the 3rd row by 7

Eliminate the 3rd column

Solution set:

x = -22/21

y = 11/3

z = -8/7

	X1	X2	X3	b
1	3	0	-1	-2
2	2	1	-3	5
3	1	2	2	4
