Solving a system of three equations
Web1. A unique solution exists if a numerical value for each variable is found that will satisfy the system of equations. 2. Some linear equations may not have a solution or have infinitely many solutions. 3. A consistent system of equations will have at least 1 solution, whereas a system with no solution is an inconsistent system.

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. WebSolve the system of equations using Cramer’s Rule: { 3 x + y − 6 z = −3 2 x + 6 y + 3 z = 0 3 x + 2 y − 3 z = −6. Cramer’s rule does not work when the value of the D determinant is 0, as this would mean we would be dividing by 0. But when D …
