Important Topics covered in Chapter 4  Linear Equations in Two Variables
NCERT solutions for class 9 maths give you the best coverage for all the topics and subtopics in this chapter. Here are some important topics covered in chapter 4.
4.1 Introduction 
4.2 Linear Equations 
4.3 Solution of a Linear Equations 
4.1 Introduction  The chapter starts off by giving a general overview of linear equations in one variable, which is covered by the previous class. It goes on to explain how linear equations in two variables relate to each other. You will also find linear equation definition in one and two variables along with examples in NCERT solutions for class 9 math chapter 4.
4.2 Linear Equations  An equation is a sum of a constant and a variable under the condition that they are equal. When the variables in the simplest form, such as x, y, z, etc., are included in the equation, it is known as a linear equation.
When you have two variables in a linear equation instead of just one, it's called a linear equation in two variables.
Example: 6y4z=9 is a linear equation in two variables.
4.3 Solution of a Linear Equation  You’ve already learned that a onevariable linear equation has a different solution. But what about a twovariable linear equation? We’ll look at that in this section.
Linear equations in two variables have 2 variables. There is a high probability of finding multiple solutions. Ex. 2x+3y = 12.
x = 3 and y = 2 because they both satisfy RHS. The solution to this equation is written as follows: (3, 2) (0, 4) (6, 0).
Therefore, it can be concluded that there may or may not be a unique solution to a linear equation in 2 variables.
