Thanks!

I also know that a matrix multiplied by its inverse is the identity matrix. would the resultant matrix of the problem above be: in one column [0 0 0 0 0 0 1 0 0 0]

I'm sure that I can just make a matrix up then find its inverse and multiply the original by the 7th column of the inverse but is there a general rule for doing this?

X is a 10x10 matrix what is X*[7th column of X's inverse]? thanks for any help you can provide!
