WebOct 6, 2024 · We can solve systems of three linear equations with three unknowns by elimination. If the process of solving a system leads to a false statement, then the system is inconsistent and has no solution. If the process of solving a system leads to a true statement, then the system is dependent and has infinitely many solutions. 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.
