If you are given a matrix and you want to determine its rref form, then do not panic. Just go by following the following key points and you will get what you seek. The first number in each row

corresponding to the RREF is x 1 = 11, x 2 = 4, x 3 = 3. The equations are already solved for the leading variables. The system has the one solution (11; 4;3). Example. Suppose that the RREF

1/ To assess whether a matrix is invertible and finally find its reverse: whenever you use the basic operations to a matrix so as to set it in the low echelon form you're really multiplying it
