How to solve systems of 3 variable equations

WebThe 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. WebExample 1: Solve the system with three variables by Cramer’s Rule. From the given system of linear equations, I will construct the four matrices that will be used to solve for the values of \large {\color {green}x} x, \large {\color {green}y} y, and \large {\color {green}z} z. Use the guide above to correctly set up these special matrices. some people seem to be born happy
