To write the matrix in reduced row-echelon form, apply elementary row operations until we obtain zeros above and below each of the leading 1's. First interchange the rows of the augmented matrix as given below. - 20 0 1 : - 1 1 0 0 1: 10 1 1 1 15 10 20 : 3416 307 Now perform the operation (-R1) (-R.)- 10 0 - -1 1 10 1: 307 20 : 3416 1 1 1 15 10 Next, perform the operations (R2 + R1) on R2 and R3 - R1) on R3. -글 : -글 : 1 0 0 0 1 10 (R2 + R1)→ (R3 - R1)→ 1. 1. : 307 1. 5 10 20 : 3416
