The Concept Map you are trying to access has information related to:
Systems of Linear Equations, Singular if they have Infinite Number of Solutions, Inconsistent if they have No Solution, Consistent if they have One Solution, Row Echelon Form which is defined as Any matrix which has 1. Any rows consisting of all zeros are at the bottom 2. In every nonzero row, the first non-zero element (called the leading entry) is in a column to the left of any other leading entries in lower rows, A Matrix Equation which means that Given a known matrix A and a known solution vector b, can one find a vector x such that Ax=b, A Matrix Equation which can be transformed using Elementary Row Operations, Elementary Row Operations such as 1. Exchanging any two rows of the coefficient matrix, Reduced Row Echelon Form which is defined as A matrix which 1. is in row echelon form 2. The leading entry in each non-zero row is a 1 3. Each column with a leading entry of 1 has only zeroes below it, Elementary Row Operations to produce Row Echelon Form, Elementary Row Operations such as 3. Adding a multiple of one row to another row
