The approach for solving a system of linear equations with three variables is comparable to the method for systems with two variables. We reduce all variables by adding the system to two equations with two variables. Once we have a system of two equations in two variables, we can eliminate a variable using addition or substitution. The result is a single-variable equation. This equation is solved to determine the value of the remaining variable. Back-substitution yields additional variable values.
