Lineaarvõrrandiks

Lineaarvõrrandiks is a mathematical term referring to a linear equation. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. The variables in a linear equation are raised to the power of one. The general form of a linear equation with one variable is ax + b = 0, where 'a' and 'b' are constants and 'x' is the variable. The goal when solving a linear equation is to find the value of the variable that makes the equation true.

In a linear equation with two variables, the general form is Ax + By = C, where A, B, and C are constants and x and y are the variables. Equations of this form represent a straight line when graphed on a coordinate plane. Solutions to such equations are pairs of (x, y) values that lie on that line. Systems of linear equations involve two or more linear equations with the same set of variables. Solving a system of linear equations means finding a set of values for the variables that satisfy all equations simultaneously. Common methods for solving systems of linear equations include substitution, elimination, and graphical methods. The concept of linear equations is fundamental in various fields of mathematics, science, and engineering due to its simplicity and wide applicability.
