Solving Systems of Linear Equations in Three Variables
Solving Algebraically. As with systems of equations in two variables, there are many methods for solving systems in three variables. If technology is present, using matrices is generally the quickest and most efficient. Otherwise, a combination of the elimination and substitution methods works well.

Substitution: solve one equation for a variable, substituting the expression you obtain into the second equation, then solving that resulting equation for a value, or . Elimination: add multiples of the equations together so that one of the variables is eliminated. Example: Solve . First, graph the equations.
