WebSep 17, 2024 · Solution. Consider the elementary matrix E given by. E = [1 0 0 2] Here, E is obtained from the 2 × 2 identity matrix by multiplying the second row by 2. In order to carry E back to the identity, we need to multiply the second row of E by 1 2. Hence, E − 1 is given by E − 1 = [1 0 0 1 2] We can verify that EE − 1 = I.
