Navodaya Class 9 Mathematics Chapter 10: Linear Equations in One Variable

What if a simple number puzzle could unlock a whole world of mathematics? That is exactly what happens when students learn Navodaya Class 9 Maths Linear Equations in One Variable. This chapter teaches students how to find unknown numbers by using simple steps and rules. Moreover, linear equations are useful in many daily-life problems, such as finding prices, ages, distances, and quantities.

For JNVST Class 9 students, a clear understanding of this topic can make problem-solving easier. Therefore, students should learn the basic rules first and then solve different types of questions. With regular practice, Navodaya Class 9 Maths Linear Equations in One Variable becomes simple and interesting.

However, Veda Academy helps students prepare for the Navodaya Class 9 exam with simple notes, important questions, model papers, and mock tests. Students can use these resources to understand concepts and practise questions regularly. They provide a platform for students that is the best coaching for Navodaya Class 9 exam preparation. 

What are Linear Equations in One Variable?

A linear equation is a mathematical statement that has an equal sign and one unknown variable. Usually, we use letters such as x or y for the unknown number. For example: x + 5 = 12. Here, x is the variable. We need to find its value. To solve the equation: x + 5 = 12
x = 12 − 5
x = 7


Thus, the value of x is 7. In Class 9 Linear Equations in One Variable, students learn how to solve equations with variables on one or both sides. Also, they learn how to check whether their answer is correct.

Important Rules for JNVST Class 9 Maths Linear Equations

Students preparing for JNVST Class 9 Maths Linear Equations should remember a few simple rules.

  1. Add the same number to both sides of an equation.

  2. Subtract the same number from both sides.

  3. Multiply both sides by the same number.

  4. Divide both sides by the same non-zero number.

  5. Keep the variable on one side whenever possible.

  6. Simplify both sides before finding the value of the variable.


The examples for linear equations are as follows: 3x + 4 = 19

First, subtract 4 from both sides: 3x = 15. Next, divide both sides by 3: x = 5. Therefore, the answer is x = 5.

How to Solve Linear Equations Step by Step

The following method can help students solve Navodaya Class 9 Maths Linear Equations in One Variable questions with confidence. This simple process is useful for JNVST Class 9 Mathematics preparation because it helps students avoid common calculation mistakes 


Step 1. Read the equation carefully: First, identify the variable and numbers in the equation.

Step 2. Simplify both sides: Next, remove brackets or combine like terms if needed.

Step 3. Move the numbers: Then, use addition or subtraction to keep the variable on one side.

Step 4. Find the variable: After that, use multiplication or division to find the value of the variable.

Step 5. Check your answer: Finally, put the value back into the original equation. If both sides are equal, your answer is correct.

Types of Navodaya Class 9 Maths Linear Equations in One Variable Questions

The JNVST Class 9 Maths Linear Equations has different types, so students need to understand all the types so they are able to answer different types.


Equations

Examples

Simple Equations

x + 8 = 20. 

x = 20-8

 x = 12

Equation with Multiplication

5x = 35

x = 7

Equations With Variables on Both Sides

4x + 3 = 2x + 13

Subtract 2x from both sides:

2x + 3 = 13

Subtract 3:

2x = 10

Therefore:

x = 5

Equations With Brackets

Students should first remove the brackets. Then, they can simplify and solve the equation step by step.

Word Problems

Finally, students should practise word problems. These questions turn real-life situations into equations. Therefore, students must read each question carefully before choosing the equation.
