Topic[FOR COMPLETE EXPLANATION OF THE TOPIC] 
1 
Introduction Teacher will write the general pair of linear equations in two
variables on the board and then explain all the components of the equations
i.e. coefficients and variables . a_{1}x + b_{1}y
= c_{1} a_{2}x +b_{2}y=c_{2} Here a_{1}, a_{2} are the coefficients of x, b_{1}, b_{2} are the coefficients of y, c_{1}, c_{2} are the constant terms , x and y are the
variables.

Graphical Solution Teacher will take an example of pair of linear equations in two variables and explain to the students the method of finding at least three solutions of each of the equation. Now on the board teacher will draw the graph of two equations on the single graph. Teacher will also give the knowledge
to the students that

3 
Now by comparing the
ratio of the coefficients, discuss the nature of solution, types of graphs
and consistency or inconsistency of equations. Teacher can take some examples
to explain this concept. 
4 
Substitution Method Now teacher will explain the Method of solving the pair of
linear equations in two variables by Substitution Method. Teacher will
explain the topic by taking 3  4 examples. After giving
complete knowledge to the students teacher will give some problems to the
students to check whether they understand the concept or not. 
5 
Elimination method Now teacher will explain the Method of solving the pair of
linear equations in two variables by Elimination method. Teacher will explain
the topic by taking 3  4 examples. After giving
complete knowledge to the students teacher will give some problems to the
students to check whether they understand the concept or not. 
6 
Cross Multiplication Method Now teacher will explain the Method of solving the pair of
linear equations in two variables by Cross Multiplication Method. Teacher will
explain the topic by taking 3  4 examples. After giving
complete knowledge to the students teacher will give some problems to the
students to check whether they understand the concept or not. 
7 
Applications After giving complete knowledge of different methods of
solving pair of linear equations in two variables teacher will help the
students to apply these methods in solving the word problems. Teacher may also
give some problems to the students for practice. 
8 
Equations Reducible to the Pair of Linear Equations Now teacher will explain the method of solving the pair of
equations which are not linear equations but can be made linear by making
some substitutions. Such equations are called Equations Reducible to the Pair
of Linear Equations. Teacher may provide
some problems from exercise 3.6 of NCERT book for practice and better
understanding 
9 
Special Equations Now Teacher will
explain the method of solving some special types of equations given in
exercise 3.7 (optional exercise) of NCERT Book 
 All important concepts related to the pair of linear equations in two variables.
