# Topics of NCERT Maths chapter 3

For a learner, it is important to clear class 10 with good rank as it is known as the foundation year of the career. There are various subjects on which the one needs to focus while being in this year. The concepts of the learner must be cleared, and at the same time, he must also be aware of presenting the facts in an effective manner. The chances are not that bright that one can learn these skills in school and hence private coaching also becomes much important.

Class 10 is popular as one of the most crucial phases in a student’s life because this is the first time when he/she is supposed to sit for the board exams. Board exams are important, and though being comparatively easier, one has to prepare for it from the start since it includes the syllabus of the last three classes. Coming to Mathematics, this subject needs a lot of practice, and the basics have to be unquestionably clear for one to score cent percentage marks. The subject is divided into Arithmetic, Algebra, and Geometry. These deal with the three aspects of Mathematics. While Arithmetic has numerical, Algebra deals with solving of equation and Geometry with the construction. The NCERT book for class 10 Mathematics is an assemblage of all the three.

The **CBSE Class 10 maths chapter 3** deals with linear equations in two variables. This is one of the very basic topics of Algebra. To define a linear equation, it can be said that when an algebra equation has terms which are constant or product of a constant and a single variable, it is called a linear equation. For example, xa+y = 0, and x and y are constant, and x is not equal to 0. This chapter specifically deals with the following topics:

Introduction

Pair of Linear Equations in Two Variables

Graphical Method of Solution of a Pair of Linear Equations

Algebraic Methods of Solving a Pair of Linear Equations

-Substitution Method: one value can be substituted with another value.

-Elimination Method: one variable is eliminated to make a simple equation.

-Cross-Multiplication Method: Values has to be put to get the value of the actual variables.

Equations Reducible to a Pair of Linear Equations in Two Variables

Summary

The maths book explains the different kinds of equations and the ways to solve them. It also amply provides one with numerical to practice.

**What is the need of the solutions?**

The NCERT solutions for class 10th maths chapter 3 provide you with the scope to practice more numerical. Practice makes a man perfect, and in the board exams, one does not have the time to think and solve. It is about solving the most number of sums in the least amount of time. The solution book has questions and solved answers. You can either practice them before your exam or just go through the solutions as a part of your revision. This will definitely ensure that you put the best of your ability to score the highest amount of marks.
