That is a possibility...but there is a neat way of creating matrices without using
Code:
\left[\begin{array}{cccc} [insert matrix here] \end{array}\right]
You can use
Code:
\begin{bmatrix} [insert matrix entries here] \end{bmatrix}
This saves me a lot of time.
For example, instead of using
Code:
\left[\begin{array}{cccc} 1&0&0&0\\0&1&0&0\\0&0&1&0\\0&0&0&1 \end{array}\right]
to generate
![\left[\begin{array}{cccc} 1&0&0&0\\0&1&0&0\\0&0&1&0\\0&0&0&1 \end{array}\right] \left[\begin{array}{cccc} 1&0&0&0\\0&1&0&0\\0&0&1&0\\0&0&0&1 \end{array}\right]](http://www.mathhelpforum.com/math-help/latex2/img/31d3d383fca61691802eaed25a45222f-1.gif)
, you can use
Code:
\begin{bmatrix}1&0&0&0\\0&1&0&0\\0&0&1&0\\0&0&0&1 \end{bmatrix
to generate

The second one elimination problem is kind of routine so no body has no interest to answer.

It may be this, or just that using eliminations on this will lead to ugly looking fraction elements!!! [as seen in my response to part a)]
