FAQs on Linear Equations in One Variable Class 8 Worksheet Maths Chapter 2

1. What is a linear equation in one variable?
Ans. A linear equation in one variable is an equation that can be written in the form ax + b = 0, where 'a' and 'b' are constants and 'x' is the variable. The highest power of the variable is 1.
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 usually involves performing operations such as addition, subtraction, multiplication, or division to both sides of the equation until the variable is alone.
3. What are some common mistakes made when solving linear equations?
Ans. Common mistakes include forgetting to apply the same operation to both sides of the equation, miscalculating during arithmetic operations, and incorrectly interpreting the signs of numbers.
4. Can linear equations have no solution or infinitely many solutions?
Ans. Yes, a linear equation can have no solution (when the lines are parallel) or infinitely many solutions (when the lines overlap). This typically depends on the coefficients of the variables in the equation.
5. What is the importance of linear equations in real life?
Ans. Linear equations are important in real life as they can model relationships between quantities, such as budgeting, calculating distances, or predicting outcomes in various fields like economics, science, and engineering.
