**NCERT Solutions for Class 9 Maths Chapter 4 Exercise 4.1 **introduces us to a linear equation with two variables. As this is the first time a linear equation with two variables is introduced in NCERT solutions for Class 9 Maths chapter 4 exercise 4.1 so chapter starts with the prerequisite of linear equation with one variable that we have learnt in an earlier class. Class 9 Maths chapter 4 exercise 4.1 is based on a very basic concept of representation of any equation in the form of a general linear equation with two variables.

NCERT Solutions for Class 9 Maths exercise 4.1 is a base builder exercise for the further exercises in the chapter linear equation with two variables and all the chapters that will be studied in further classes. In exercise 4.1 Class 9 Maths, we have given a rough idea about general equations and it’s representation.

9th class maths exercise 4.1 answers are authored by subject experts at Careers360, and presented in a comprehensible and detailed manner. Each class 9 maths chapter 4 exercise 4.1 comprises a total of two questions with multiple parts. PDF versions of these solutions are readily accessible, allowing students to download and utilize them offline at no cost. Along with Class 9 Maths chapter 4 exercise 4.1, the following exercises are also present.

** Answer: **

Let the cost of a notebook be Rs * x * and that of a pen be Rs * y * .

According to the given condition: The cost of a notebook is twice the cost of a pen.

Thus,

Given :

Here , a=2, b=3 and c =

Given:

Here ,

a=1,

c = -10

Given :

Here , a= -2, b=3 and c = -6

Given :

Here , a= 1, b= -3 and c =0

Given :

Here , a=2, b= 5 and c =0

Given :

Here , a= 3, b=0 and c =2

Given :

Here , a=0, b= 1 and c = -2

Given :

Here , a=2, b= 0 and c = -5

NCERT syllabus Class 9 Maths chapter 4 exercise 1 is broadly based on the basis of linear equations with two variables. Linear Equations with Two Variables are also used in real-life applications as mentioned before in exercise 4.1 Class 9 Maths in the NCERT book. Two variable equations show us the dependence of two variables on each other for example run scored by player x and run scored by player y a linear equation will show how both of them are related and this is how we can use them in real life. We can also use a linear equation in our daily life by applying it to the things we buy from stationery such as pen and pencil as covered in NCERT solutions for Class 9 Maths exercise 4.1 question 1. NCERT solutions for Class 9 Maths exercise 4.1 covers all types of basic questions that can be formed on linear equations with two variables.
