Access Class 8 Mathematics Chapter 2 – Linear Equations in One Variable

A declaration that two algebraic expressions with one or more variables are equivalent. $x+2=3$ is an example of having more than one variable.

An Equation in Linear Form One Factor to Consider: The expressions that make up an equation with a single variable and one as the largest power of the variable in the equation.

An algebraic equation is a variable-based equivalence. It states that the value of the expression on one side of the equality sign is the same as the value of the expression on the other side of the equality sign.
Linear equations in one variable are what we learn in Classes VI, VII, and VIII. The expressions that make up the equation in such equations only have one variable. The equations are also linear, which means that the greatest power of the variable appearing in the equation is 1.
Any rational integer can be used as the answer to a linear equation. Both sides of an equation can have linear expressions. There was just one number on one side of the equation in the equations we covered in Classes VI and VII. Variables, like integers, can be moved from one side of the equation to the other.
In certain cases, the expressions that comprise equations must be simplified before they can be solved using standard procedures. Some equations may not be linear, to begin with, but by multiplying both sides of the equation by an appropriate expression, they can be made linear.
Linear equations have a wide range of applications; they may be used to answer issues involving numbers, ages, perimeters, and combinations of money notes, among other things.

FAQs on CBSE Class 8 Revision Notes Maths Chapter 2 Linear Equations in One Variable (Free PDF Download)

1. What is the difference between a constant and a variable?

A constant is a number whose value is fixed or that is constantly the same. Its degree is 0. A variable, often represented by a letter, represents some unknown value that is not fixed.

2. What kind of problems can be solved using ‘Linear Equations in One Variable’?

Linear equations can be used to solve:

Age-related problems
Geometry-related problems
Money, percentage-related problems
Work, time, and wage-related problems
Calculate speed sums, perimeters, and areas

3. Can a linear equation have more than one solution?

No, a linear equation in one variable can have only one solution. The solution can be a real number, and it may or may not be unique.

4. What is the role of the balance method in solving linear equations?

The balance method is a visual representation technique used to solve linear equations. It involves keeping both sides of the equation balanced by performing the same operation on both sides. The aim is to isolate the variable term and find its value.

5. Can we solve word problems using linear equations?

Yes, linear equations can be used to solve word problems. By translating the given problem into an equation, you can solve for the unknown variable and find the solution to the problem.
