How to Determine if a Matrix is invertible - Study.com
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.
