WebYes, matrix A multiplied with it's inverse A-1 (if it has one, and matrix A is a square matrix) will always result in the Identity matrix no matter the order (AA^-1 AND A^ (-1)A will give I, … WebOnce in this form, the possible solutions to a system of linear equations that the augmented matrix represents can be determined by three cases. Case 1. If \text {rref} (A) rref(A) is the identity matrix, then the system has a unique solution. When read row by row, this augmented matrix says x = -1, y = 2, x = −1,y = 2, and z = 3: z = 3:

WebOct 6, 2024 · Set the entry in row 2, column 1 of the new matrix equal to the corresponding entry of the identity, which is 0. 1a − 2c = 1 R1. 2a − 3c = 0 R2. Using row operations, multiply and add as follows: ( − 2)R1 + R2 → R2. Add the equations, and solve for c. 1a − 2c = 1 0 + 1c = − 2 c = − 2.
