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. Back-substitute to solve for a. WebAnother way to find the multiplicative inverse is by augmenting with the identity. When matrix A A is transformed into I I, the augmented matrix I I transforms into A−1 A − 1. Perform row operations with the goal of turning A A into the identity. Switch row 1 and row 2. Multiply row 2 by −2 − 2 and add to row 1. WebNow, if A is matrix of a x b order, then the inverse of matrix A will be represented as A-1. Now the question arises, how to find that inverse of matrix A is A-1.
