In Exercises 5–9, find the determinant of the given elementary matrix by inspection. 5. Answer: 6. 7. Answer: 8. 9.Nov 22, 2014 at 6:20. Consider the row operation R1-R2. If you replace R1 by R1-R2, the sign of the determinant does not change, because you did not change the sign of R1. But, what you did was to replace R2 by R1-R2, which changed the sign of the determinant. In effect, you multiplied R2 by negative one, and then added another row to it.Use either elementary row or column operations, or cofactor expansion, to find the determinant by hand.

A linear system is said to be square if the number of equations matches the number of unknowns. If the system A x = b is square, then the coefficient matrix, A, is square. If A has an inverse, then the solution to the system A x = b can be found by multiplying both sides by A −1: The determinant of a product of matrices is equal to the product of their determinants, so the effect of an elementary row operation on the determinant of a matrix is to multiply it by some number. When you multiply a row by some scalar λ, that’s the same as multiplying the matrix by a diagonal matrix with λ in the corresponding row and 1 s ...

Step-by-step solution. 100% (9 ratings) for this solution. Step 1 of 4. Using elementary row operations, we will try to get the matrix into a form whose determinant is more easily found, i.e. the identity matrix or a triangular matrix. ? -3 times the first row was added to the second row.By Theorem \(\PageIndex{4}\), we can add the first row to the second row, and the determinant will be unchanged. However, this row operation will result in a row of zeros. Using Laplace Expansion along the row of zeros, we find that the determinant is \(0\).
