Explanation Given information: The system of equations is as follows. 30 x + 20 y − 10 z = 30 4 x − 2 y − 6 z = 4 − 5 x + 20 y − 25 z = − 5 Calculation: Show the augmented matrix for the system of equations as shown below. [ 30 20 − 10 30 4 − 2 − 6 4 − 5 20 − 25 − 5 ] Apply Gaussian elimination in the system of equations as shown below. Apply the row operations as shown below. [ 30 20 − 10 30 4 − 2 − 6 4 − 5 20 − 25 − 5 ] = [ 1 2 3 − 1 3 1 4 − 2 − 6 4 − 5 20 − 25 − 5 ] R 1 → R 1 30 = [ 1 2 3 − 1 3 1 0 − 14 3 − 14 3
