Knowledge points: Concepts related to linear equations (groups) of three variables

A system of equations containing three unknowns, and the degree of the terms containing the unknowns is linear, is called a system of linear equations in three variables.

Necessary conditions for a system of linear equations in three variables:

(1) is an integral equation;

(2) Contains three unknowns in total;

(3) All three are linear equations;

(4) United together.

Summarize

When solving a system of three-dimensional linear equations, it doesn't matter which "element" is eliminated, and the result will be the same. We should choose the simplest solution method by observing the system of equations. Method 1 in this question is the simplest. It is necessary to flexibly determine the elimination steps and elimination methods according to the characteristics of each equation in the system of equations, and do not eliminate blindly.

System of linear equations in three variables PPT, part 3 content: Class summary

The basic idea of ​​solving a system of three-dimensional linear equations is still elimination, which is a method to simplify complex problems. The purpose is to use substitution or addition and subtraction to eliminate an unknown number, thereby changing the ternary into a binary, and then solve the system of linear equations of two variables to find two unknowns, and finally find another unknown number. The basic process is:
