Example 1 Evaluate the following determinant. First find the minor determinants. The solution is To use determinants to solve a system of three equations with three variables (Cramer's Rule), say x , y , and z , four determinants must be formed following this procedure: 1. Write all equations in standard form. 2. Create the denominator determinant, D , by using the coefficients of

Create the x-numerator determinant, D x , the y-numerator determinant, D y , and the z-numerator determinant, D z , by replacing the respective x , y , and z coefficients with the constants from the equations in standard form and evaluate each determinant. The answers for x , y , and z are as follows:...
