These problems come from section 2.1 in the 11th edition of the text:

- numbers 1-28

These exercises are meant to help you get used to the elementary row operations we’re allowed to do when we use Gauss Jordan Elimination to solve a linear system.

For practice on Gauss Jordan Elimination do:

- section 2.1 numbers 39, 43, 45, 49
- section 2.2 numbers 17, 27, and 37
