Explanation Given information: The system of linear equations is { 49 x − 27 y + 52 z = − 145.0 27 y + 43 w = − 118.7 − 31 y + 42 z = − 72.1 73 x − 54 y = − 132.7 . Calculation: The given system of linear equations is { 49 x − 27 y + 52 z = − 145.0 27 y + 43 w = − 118.7 − 31 y + 42 z = − 72.1 73 x − 54 y = − 132.7 . Rearrange the above system of equations as, { 49 x − 27 y + 52 z + 0 w = − 145.0 0 x + 27 y + 0 z + 43 w = − 118.7 0 x − 31 y + 42 z + 0 w = − 72.1 73 x − 54 y + 0 z + 0 w = − 132.7 Therefore, the augmented matrix of the given system of equations is, [ 49 − 27 52 0 − 145.0 0 27 0 43 − 118.7 0 − 31 42 0 − 72.1 73 − 54 0 0 − 132.7 ] To reduce the above system of linear equations in to row reduced echelon form first turn on the graphing calculator and press 2nd and x − 1 button simultaneously
