    • 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.
