Your Notes Solve the system. x 2y 2z 4 Equation 1 2x 2y 4z 8 Equation 2 2x 2y 4z 8 Equation 3 Rewrite the linear system in three variables as a linear system in two variables. x 2y 2z 4 Add the first equation 2x 2y 4z 8 to the second. New Equation 1 2x 2y 4z 8 Add the second equation 2x 2y 4z 8 to the third. New Equation 2 The result is a system of linear equations in two variables.

Tutorial 49: Solving a System of Linear Equations in Two Variables looked at three ways to solve linear equations in two variables. Solution of a System In general, a solution of a system in three variables is an ordered triple ( x, y, z ) that makes ALL THREE equations true.

Solve the two equations from steps 2 and 3 for the two variables they contain. Substitute the answers from Step 4 into any equation involving the remaining variable. Check the solution with all three original equations. Example 1. Solve this system of equations using elimination. All the equations are already in the required form.
