Cramer's Rule ― Multilinearity and Alternating Property of Determinants

We derive Cramer's Rule using the multilinearity and alternating property of the determinant. While we focus on the 2×2 case, the argument extends naturally to the general n×n case. Note 1: 2×2 determinant The determinant of the matrix a b c d is defined as ad - bc. Note 2: Multilinearity of the determinant The determinant is linear with respect to each column. Note 3: Alternating property of the determinant The determinant of a matrix with two identical columns is zero.
