NCERT Solutions for Class 10 maths Chapter 3 Pair of Linear Equations in Two Variables

This chapter explains the concept of Pair of Linear Equations in Two Variables. An equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers, and a and b are not zeros, is called a linear equation in two variables x and y. This chapter has a total of 7 parts, and in these exercises, different methods of solving the pair of linear equations are described. Part 1 describes how to represent a situation algebraically and graphically. Part 2 explains the methods of solving the pair of the linear equation through Graphical Method. Part 3 4,5 and 6 describe the Algebraic Method, Elimination Method, Cross-Multiplication Method, Substitution Method, respectively. Part 7 is optional, which contains all types of questions. Students must practise these exercises to master the method of solving the linear equations.
