WebMar 24, 2024 · Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. As shown by Cramer's rule, a nonhomogeneous system of linear equations has a unique solution iff the determinant of the system's matrix is nonzero (i.e., the matrix is nonsingular). For example, eliminating x, y, and z from the … WebThe reduced row echelon form of the matrix is the identity matrix I 2, so its determinant is 1. The second-last step in the row reduction was a row replacement, so the second-final matrix also has determinant 1. The previous step in the row reduction was a row scaling by − 1 / 7; since (the determinant of the second matrix times − 1 / 7) is 1, the determinant … northern ireland diesel prices
