3. Write the system of equations as an augmented matrix and use Gauss- Jordan Elimination to re-write the augmented matrix in Reduced Row Echelon Form. Give the solution set for the system, if any. Clearly state if no solution exists. If the system has infinitely many solutions, describe the solution set for any number 1:. For full credit, ALL row operations must be shown. Clearly label your answer. || U1 4x1 2x2 + 2x3 6 6x1 + 3x2 3x3 10x1 5x2 + 9x3 = 4
