How to solve row operations
WebMar 5, 2024 · Much use is made of the fact that invertible matrices can be undone with EROs. To begin with, since each elementary row operation has an inverse, M = E − 1 1 E − 1 2 ⋯. while the inverse of M is. M − 1 = ⋯E2E1. This is symbolically verified as. M − 1M = ⋯E2E1E − 1 1 E − 1 2 ⋯ = ⋯E2E − 1 2 ⋯ = ⋯ = I. WebNow, I will transform the RHS matrix to an upper diagonal matrix. I can exchange the first and the last rows. Exchanging any two rows changes the sign of the determinant, and therefore. det [ 2 3 10 1 2 − 2 1 1 − 3] = − det [ 1 1 − 3 0 1 1 0 0 15] The matrix on the RHS is now an upper triangular matrix and its determinant is the product ...
