Math 1313Section 3.2A System of Equations That Has No SolutionIn using the Gauss-Jordan elimination method the following equivalent matrix was obtained (notethis matrix is not in row-reduced form, let’s see why):---100014401111Look at the last row.It reads:0x + 0y + 0z = -1, in other words, 0 = -1!!!This is never true.Sothe system is inconsistent and has no solution.Mark D for question 4Systems with No Solution
