How to solve system of equations with 3 variables.
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: Write all equations in standard form. Create the denominator determinant, D, by using the coefficients of x, y, and z from the equations and evaluate it.
