How To Easily Solve A 5x5/5x6 Matrix / system with 5 unknowns? I tried to use the inverse and multiply it by B, but the inverse is filled with strange decimals, and the answer isn't right. I can do it via reduced low-echelon form, but it requires me to write down 23 transformed matrices. The matrix is as in the following post.

The answer should be (0,1,2,-1,0)

If you do it by hand,  then transform the matrix to rref form.
(which is probably how a computer would solve it.)
