Select a different set of two equations and eliminate the same variable as in Step 2.Choose a variable to eliminate then choose any two of the three equations and eliminate the chosen variable.Write all the equations in standard form cleared of decimals or fractions.To use elimination to solve a system of three equations with three variables, follow this procedure: The two most straightforward methods of solving these types of equations are by elimination and by using 3 × 3 matrices. Systems of equations with three variables are only slightly more complicated to solve than those with two variables. Linear Equations: Solutions Using Elimination with Three Variables
