NCERT Solutions for Class 8 Maths Chapter 2 Linear Equations in One Variable Chapter 2 of NCERT is the continuation of the concept of algebraic expressions and equations that the students learned in lower classes. In this chapter, the students learn with equations having one variable. Some of the main topics or concepts that are discussed in this chapter include: 1. An algebraic equation is an equality involving variables. It says that the value of the expression on one side of the equality sign is equal to the value of the expression on the other side. 2. A linear equation may have for its solution any rational number. 3. An equation may have linear expressions on both sides. 4. Just as numbers, variables can also be transposed from one side of the equation to the other. 5. Occasionally, the expressions forming equations have to be simplified before we can solve them by usual methods. Some equations may not even be linear, to begin with, but they can be brought to a linear form by multiplying both sides of the equation by a suitable expression. 6. The utility of linear equations is in their diverse applications; different problems on numbers, ages, perimeters, a combination of currency notes, and so on can be solved using linear equations.
