I'm still having trouble with Guassian elimination and finding the Inverse of a Matrix. I tend to get confused with the switching of the rows or factoring out something.(adsbygoogle = window.adsbygoogle || []).push({});

Example matrix

1 1 1 | 1

1 1 -2 | 3

2 1 1 | 2

so it's a system of linear equations and I must solve for x, y, and z.

I was wondering is someone could help show the steps in solving these matrices as well as explain finding the solution to the inverse matrix.

I know that to find the inverse, the Matrix must be dotted by the Identity matrix.

Thanks
