Row of operation to an Augmented Matrix

- September 24th 2007, 10:47 PMjay123
is there any way you can help me.

I know there is a system to solving these equations. such as add the 1st two roles to get the 1st row but i cant remember the rest. - September 25th 2007, 04:46 AMWWTL@WHL
Are you talking about echelon form?

The most common way (I think) of doing this is finding the inverse of the matrix. Have you learned how to do that? - September 25th 2007, 08:39 AMJhevon
yes, that's what he's talking about. i will go all the way to reduced row echelon, i like doing that.

ok, here goes. i will not type what i did to get from one step to another, so if you don't understand something, just ask.

The augmented matrix is:
