FAQs on Flashcard: Linear Equations in One Variable Video Lecture - Mathematics (Maths) Class 8

1. What is a linear equation in one variable?
Ans. A linear equation in one variable is an equation that can be expressed in the form ax + b = 0, where 'a' and 'b' are constants, and 'x' is the variable. The graph of this equation is a straight line.
2. How do you solve a linear equation in one variable?
Ans. To solve a linear equation in one variable, you isolate the variable on one side of the equation. This typically involves performing inverse operations, such as adding or subtracting a constant, and then dividing or multiplying by the coefficient of the variable.
3. What are some examples of linear equations in one variable?
Ans. Examples of linear equations in one variable include: 1) 2x + 3 = 7 2) -5x = 10 3) x - 4 = 0. Each of these can be solved for 'x' to find its value.
4. What is the importance of linear equations in real-life applications?
Ans. Linear equations are important in real-life applications as they can model relationships between quantities. For example, they can be used in budgeting, calculating distances, and in various fields such as physics and economics to describe linear relationships.
5. How can I check if my solution to a linear equation is correct?
Ans. To check if your solution to a linear equation is correct, substitute the value you found for the variable back into the original equation. If both sides of the equation are equal, then your solution is correct.
