Linear equations with one variable is a chapter in NCERT Maths that deals with solving equations that have only one variable. In simpler terms, it is about finding the value of an unknown number in an equation.

The chapter starts with an introduction to equations and how they are used in our daily lives. It then moves on to explain what a linear equation is and how to solve it. A linear equation is an equation that can be written in the form ax + b = c, where a, b, and c are constants and x is the variable.

The chapter then explains how to solve linear equations using the method of balancing. This involves performing the same operation on both sides of the equation to isolate the variable. For example, if we have the equation 2x + 3 = 7, we can subtract 3 from both sides to get 2x = 4, and then divide both sides by 2 to get x = 2.

The chapter also covers some important concepts related to linear equations, such as the use of variables, coefficients, and constants. It also explains how to solve word problems using linear equations, which involves translating the problem into an equation and then solving it.

Overall, the chapter on linear equations with one variable is an important foundation for understanding algebra and solving more complex equations in the future.
