Question: Identifying identical rows in a matrix

I have a problem where I am performing some matrix operations and the resulting matrix is of rank n-1, where n is the order of the matrix. I want to solve M*x=x, where M is the resulting matrix. Since teh order of M is n-1, I keep getting zero values for all but two of the variables. What is the best way to get around this problem? I am a Maple novice. Please let me know how to do it in Maple. Thanks.
