What is the meaning of mathematical equation?
An equation is an equation that represents the equal relationship between two mathematical expressions, and there is usually an equal sign "=" between them. Equations do not need reverse thinking, but can be listed directly, including unknowns. It has many forms, such as one-dimensional linear equation, two-dimensional linear equation and so on. Defining an equation with unknowns is called an equation. The definition of linear equation of one variable is called linear equation of one variable. The usual form is kx+b=0(k, b is constant, k≠0). Binary linear equation (group) Definition of binary linear equation: Binary linear integral equation with exponent 1 is called binary linear equation. Definition of binary linear equations: An equation group consisting of two binary linear equations is called binary linear equations. Solution of binary linear equation: the values of two unknowns that make the values of both sides of binary linear equation equal are called the solutions of binary linear equation. Solutions of binary linear equations: Two common solutions of binary linear equations are called solutions of binary linear equations.
