## Homework Statement

a)Use Gauss-Jordan elimination to find the inverse of A =

[ 2 1 4 ]

[ 1 1 2 ]

[ -2 -3 -2 ]

b) Use the result from part a) to find the solution of the following system.

5x+2y-3z = 5

x+y-z = -1

-3x-y+2z = 2

## Homework Equations

## The Attempt at a Solution

My problem is not with part a), I quite easily found the inverse of the matrix. What I am not understanding is what exactly they are asking me to do for part b). How can I use the inverse of one matrix to solve for another? Any help is greatly appreciated.
