### Linear Equations in One Variable (Ex 8.4)- RD Sharma Solution

Class 7 Maths Chapter 8 Linear Equations In One Variable Solution are provided here with clear step-by-step explanations by RD Sharma. These Linear Equations In One Variable Solution are incredibly popular among Class 7 students since they are useful for rapidly completing homework and preparing for exams. All problems and answers from Chapter 8 of the RD Sharma Solutions Book for Class 7 Maths are available here for free. All of Vedantu's RD Sharma Solutions for Class 7 Maths have been prepared by experts and are 100 % accurate.

The simplest equation used to represent and solve for an unknown quantity is a linear equation in one variable. It's simple to depict graphically since it's always a straight line. A linear equation is a simple technique to convey a mathematical proposition. Unknown quantities can be represented by any variable or symbol, however, in most cases, the unknown quantity in a linear equation in one variable is represented by the variable 'x.' A collection of simple strategies is used to solve a linear problem. To determine the final value of the unknown quantity, the variables are isolated on one side of the equation and the constants are isolated on the other side of the equation.

## FAQs on RD Sharma Class 7 Solutions Chapter 8 - Linear Equations in One Variable (Ex 8.4) Exercise 8.4

1. What topics are covered in RD Sharma Class 7 Solutions Chapter 8 - Linear Equations in One Variable (Ex 8.4) Exercise 8.4 - Free PDF?

Linear Equations in Chapter 8 There are four exercises in one variable. The answers to all of the problems in these exercises can be found in RD Sharma Solutions for Class 7. The following are some of the themes covered in this chapter:

• Equation – a statement of equality that involves one or more literals

• Linear equations – an equation in which the highest power of the variables involved is 1

• The solution of an equation in the trial and error method

• Systematic method

• Equations involving subtraction

• Equations involving multiplication

• Equations involving division

• Transposition method

• Applications of linear equations to practical problems

2. What is RD Sharma Class 7 Solutions Chapter 8 - Linear Equations in One Variable (Ex 8.4)?

The linear equation in one variable is written as ax+b = 0, with a and b being two integers and x being a variable. It has only one solution. 2x+3=8, is a single-variable linear equation, for example. As a result, there is only one solution to this equation, which is x = 5/2. A linear equation in two variables, on the other hand, has two solutions.

This lesson explored the notion of a linear equation in one variable, including its definition, answers, examples, word problems, and worksheet questions. This is an important topic for pupils in Class 7. So, what is the definition of a one-variable equation?

A linear equation with a maximum of one variable of order one is known as a one-variable linear equation. The formula is axe + b = 0, using x as the variable.

There is just one solution to this equation. Here are a few examples:

• 4x = 1

• 44x-1=0

• 4x+9=-11

3. How to solve Class 7 Solutions Chapter 8 - Linear Equations in One Variable (Ex 8.4) Exercise 8.4? What are important points to remember?

The most basic rule for solving linear equations is to add, subtract, multiply, or divide the same term into both sides of the equations to determine the value of the variable. The following are the stages of solving one-variable linear equations:

• By adding or subtracting the identical term on both sides of the equation, isolate the variable term on one side.

• Multiply or divide both sides with the variable's coefficient so that the variable is only on one side of the equation.

• Reduce the problem to its simplest form, "x=c."

Important points to remember are-

The following considerations assist us in summarizing the principles involved in one-variable linear equations.

• In linear equations, the degree of the variable should be exactly one.

• A linear equation in one variable has a straight line as its graph, which might be horizontal or vertical.

• Any quantity added, subtracted, multiplied, or divided into both sides of a linear equation in one variable has no effect on the solution.
