The concept of a system of linear equations in three variables

Summary

In this system of equations, x+y+z=23 and 2x+y-z=20 both contain three unknowns, and the terms of the unknowns have degrees of 1. Such equations are called linear equations of three variables.

Like this, a set of equations composed of three linear equations containing three unknowns is called a system of linear equations in three variables.

Solutions to systems of linear equations in three variables

The common solution of each equation in a system of linear equations in three variables is called the solution of this system of linear equations in three variables.

System of linear equations in three variables PPT, the third part: practice in class
