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.

System-of-Equations Word Problems (page 1 of 2) Many problems lend themselves to being solved with systems of linear equations. In "real life", these problems can be incredibly complex. This is one reason why linear algebra (the study of linear systems and related concepts) is its own branch of mathematics.
