How do I write the matrix #((4,3,7),(1,1,5),(4,5,7))# in reduced row echelon form?
If your question is correct, then your system is inconsistent because it reduces to the identity matrix and you get
Again, if your question is correct, you have an overdetermined system of linear equations, that is:
For a regular system of linear equation, you would have an
My guess is that your question is incorrect and you are missing the constants from your matrix.
