Working through the steps in getting to the Row Echelon form and I’m just not understanding the last step. The last step, highlighted in the image below, says to divide the second row by the left most co-efficient; I can’t figure out how we end up with 1 in the bottom right corner as a result of a division.

I’m sure I am missing something simple - any thoughts?

Hi @Stevehh250,

For this step:

We take the leftmost non-zero coefficient in the second row which is -0.95, since the values in the row are [0, -0.95], and the first value is a 0.

Then, dividing [0, -0.95] by -0.95 will give us:

[0 / -0.95, -0.95 / -0.95]

= [0, 1]

I hope this helps!

Thanks a bunch for that - perfect (my wife showed me where I was going wrong as well). That will teach me to read the text properly - the leftmost, not just the left.

Thanks Joseph - appreciate it.
