Question 1008315
This would be a pain to do by hand. If you must do it by hand, then I suggest using row reduction. 


This solver


<a href = "http://www.math.odu.edu/~bogacki/lat/">http://www.math.odu.edu/~bogacki/lat/</a>


will help you step by step. Here's what you do


Step 1) Click the link shown above


Step 2) Click "Enter"


Step 3) Click the "Calculating the inverse using row operations" link (it's under "Systems of linear equations and matrices")


Step 4) Select "5" for the drop down menu, then hit "submit" to set up a blank 5x5 matrix


Step 5) Enter your values. One number per box. After each number is in the right spot, hit "submit"


The solver will then give you the final answer. It also shows you the step by step method to go from point A to point Z (and everything in between). You'll have to click the "Show details" button to get all the steps to show up. 


Let me know if this helps or not. Also, let me know if you get stuck anywhere. Thanks.




Edit: This tutor has a great example on how to find the inverse of a 4x4 matrix

the tutor follows the same basic steps as the computer solver (at the first link I posted) does.
