Three by three systems of linear equations are also used to solve real-life problems. The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem.

Write equations for a system, given a word problem or a practical problem, and solve. The Algebra Files: A system of equation is a set of two or more equations, and the solution to a system is the point that satisfies all of the equations in that system. This means that the solution point is the point at which the equations intersect.

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.
