FAQs on NCERT Solutions for Class 7 Maths Chapter 2 - Linear Equations in One Variable: Exercise 2.2 (Ques 1-3)
| 1. How to solve linear equations in one variable? |  |
Ans. To solve a linear equation in one variable, isolate the variable on one side of the equation and simplify the other side. Perform the same operations on both sides of the equation to maintain equality. Finally, solve for the variable by performing any necessary operations.
| 2. What is the importance of linear equations in one variable? | |
Ans. Linear equations in one variable are important as they help in solving problems related to real-life situations, such as calculating distances, finding unknown quantities, and determining the relationship between variables. They provide a fundamental understanding of algebra and are widely used in various fields like physics, economics, and engineering.
| 3. Can a linear equation in one variable have more than one solution? | |
Ans. No, a linear equation in one variable can have only one solution. This is because a linear equation represents a straight line, and it intersects the x-axis at only one point. Hence, there can be only one value of the variable that satisfies the equation and makes it true.
