In earlier classes, you have come across several algebraic expressions and equations. In
this chapter, you’ll learn about linear equations in one variable. A linear equation is an
equation of a straight line, consisting of one variable. The highest power of the variable
is 1. These variables are solved with the help of basic algebraic operations. Linear
equations have diverse applications such as finding numbers, parameters, ages,
currency notes, finding income over time, predicting profit, budgeting, making sales
predictions and more.
2.1 Introduction
2.2 Solving Equations which have Linear Expressions on one Side and Numbers on the
Other Side
2.3 Some Applications
2.4 Solving Equations having the Variable on Both Sides
2.5 Some More Applications
2.6 Reducing Equations to Simpler Form
2.7 Equations Reducible to the Linear Form
Section 2.2 – In this section, you’ll learn the technique of solving equations, which have
linear expressions on one side and numbers on the other side.
Section 2.3 – In this section, you’ll study some very useful applications of rational
numbers such as finding the age, coins of each denomination, finding the length of a
rectangle, finding the multiples and much more.
Section 2.4 – In this section, you’ll learn how to solve linear equations, which have
expressions with variables on both sides.
Section 2.5 – In this section, you’ll study some more applications of linear equations,
such as- how to find the original number if the digits are interchanged, finding the
present ages, finding the dimensions of a plot and more.
Section 2.6 – In this section, you’ll acquire knowledge on how to simplify the form of
the given equation using LCM (Least Common Multiple).
Section 2.7 – In this section, you’ll get in-depth knowledge about the equations, which
are reducible to the linear form.
Several examples are provided, along with their solutions for a clear understanding of
linear equations in one variable. To know more about the Class 8 Maths Chapter 2 Linear Equations in One Variable, you should explore the exercises below. You can also download the Linear Equations in One Variable Class 8 NCERT Solutions PDF, solved by expert Maths trainers.
