In Graphical Method we will be drawing graphs of two equations and intersection point is called the solution of the graph. We all know that a graphical representation of a linear equation in two ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

Some important points to revise from the chapter are: • An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in ...

In this article you will get the NCERT solutions to Class 9 Mathematics Chapter 4, Linear Equations in two Variables. Our experts have prepared these questions in step wise structure. All the ...

The chapter explains the general form of such equations and their solutions, which are represented as ordered pairs of numbers (x, y). The graphical representation of these equations on the Cartesian ...

A solution of this system is a list of values for the \(x_i\)s such that when we substitute them into (2.2), the equation holds. A system of linear equations is consistent if it has a solution, ...
