Hi,

What is the difference between elementary row operations, Gaussian Elimination, and Gauss-Jordan Elimination?

I am confused between these 3 concepts.

For operations on rows on augmented matrices using elem. row operations, they said:

Their example wasn't clear to me though, so I don't understand the steps for that.

- Multiply a row through by a nonzero constant
- Interchange 2 rows
- Add a multiple of one row to another
