Solve the system calculator 3x3
Linear Systems and Calories
In this activity, you will create a new document to solve a linear system of three equations in three unknowns. You will learn three different strategies to solve the same linear system, one utilizing the Algebra menu of the Calculator application and each of the other two utilizing a Matrix. Any of the three methods can be used to solve a system of equations.

The standard technique to solve a system of equations can be simplified as follows: Given two equations in n variables, one can typically produce one equation in n-1 variables by eliminating one variable. This is done by picking a variable to eliminate and multiplying each equation by an appropriate factor, and then adding the two equations together. For example, if we have: 3x – 2y + z = 7 ...

A 33 system of linear equations can also be solved by using the inverse matrix method. Because this process is very long and cumbersome to do algebraically, it is normally done using a graphing calculator. Solving a 33 system using technology will be presented in the Appendix. Example 2: Solve the following system of linear equations algebraically:
