One-dimensional linear equation refers to an equation with only one unknown number, the highest order of which is 1, and both sides are algebraic expressions. A linear equation with one variable has only one root.
One-dimensional linear equation can solve most engineering problems, travel problems, distribution problems, profit and loss problem, integral table problems, telephone billing problems and digital problems.
In16th century, after the mathematician David founded symbolic algebra, he put forward the propositions of shifting terms and division of the same equation.
1859, mathematician Li officially translated this kind of equation into linear equation? .
If an equation contains two unknowns and all the unknowns are linear, then the whole equation is called binary linear equation, and it has infinite solutions. If conditions are imposed, there is a finite solution.
Extended data:
If an equation contains two unknowns, and the number of unknowns is 1, then the whole equation is called binary linear equation and has countless solutions. If conditions are added, there is a finite solution.
The general form of binary linear equation: ax+by+c=0, where a and b are not zero, which is the definition of binary linear equation.
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.
Definition of binary linear equation: There are two unknowns in the equation, the degree of the term containing each unknown is 1, and a * * * has at least two equations.
Solution of binary linear equations: The common solution of two binary linear equations is called the solution of binary linear equations.
