Explanation Given: [ 1 2 2 3 | 1 − 1 ] → R 2 − 2 R 1 [ 1 2 ⋅ ⋅ | 1 ⋅ ] → − R 2 [ 1 2 ⋅ ⋅ | 1 ⋅ ] → R 1 − 2 R 2 [ 1 0 0 1 | − 5 3 ] Calculation: Consider the matrix, [ 1 2 2 3 | 1 − 1 ] → R 2 − 2 R 1 [ 1 2 ⋅ ⋅ | 1 ⋅ ] Apply the first operation R 2 → R 2 − 2 R 1 in the above matrix. [ 1 2 2 3 | 1 − 1 ] → R 2 − 2 R 1 [ 1 2 0 − 1 | 1 − 3 ] Now, consider the matrix. [ 1 2 0 − 1 | 1 − 3 ] → R 2 → ( − ) R 2 [ 1 2 ⋅ ⋅ | 1 ⋅ ] Apply the operation R 2 → ( − 1 ) R 2 in the above matrix
