Learn More about Pair of Linear Equations in Two Variables
Students must remember what they have studied in the designated chapter through the NCERT Solutions For Class 10 Maths Chapter 3 Exercise 3.1. Students of Class 10 learn about the general form of a pair of linear equations. Students also learn how linear Equations can be represented through graphs and algebra. The graphical method of representation is done by drawing two lines representing the equations on a graph paper or Cartesian plane. Extensively, the nature of these lines and their interaction represents the nature of the solution for these equations. The nature of solutions for equations could be consistent or inconsistent depending on the nature of their graph. Moreover, there is a detailed discussion of algebraic methods for solving linear equations in detail.
Three algebraic methods of solution are mentioned in the chapter namely the substitution method, the elimination method and the cross multiplication method. In addition to the method of solution for a pair of linear equations, this chapter also helps students learn how to perceive a pair of linear equations and the nature of its solution algebraically. Three cases have been given in the chapter regarding the identification of which pairs of linear equations could be considered consistent or inconsistent. This chapter also educates about situations which can be mathematically represented through a graph or algebraically using linear equations at two variables. These situations may not be linear to start with but they can be reduced to a pair of linear equations by altering them.

Q.1 Aftab tells his daughter, “Seven years ago, I was seven times as old as you were then. Also, three years from now, I shall be three times as old as you will be.” (Isn’t this interesting?) Represent this situation algebraically and graphically.
Ans.
Let the present age of Aftab and his daughter be x years and y years respectively.
So, seven years ago,
Aftab’s age = (x–7) years and his daughter’s age = (y–7) years
According to the question,
x–7 = 7(y–7)
or x – 7y + 42 = 0
Three years hence,
Age of Aftab = (x + 3) years
Age of daughter = (y + 3) years
According to the question,
x + 3 = 3(y + 3)
or x – 3y – 6 = 0
Hence, the given information is represented algebraically by the two equations below.
x – 7y + 42 = 0
x – 3y – 6 = 0
To represent these equations graphically, we need at least two solutions for each equation. We write these solutions in table.
x – 7y + 42 = 0
or x = 7y – 42
x  0  –7  7 
y  6  5  7 
Also,
x – 3y – 6 = 0
or x = 3y + 6
x  0  –3  3 
y  –2  –3  –1 
The graphical representation is given below.
Q.2 The coach of a cricket team buys 3 bats and 6 balls for ₹ 3900. Later, she buys another bat and 2 more balls of the same kind for ₹ 1300. Represent this situation algebraically and geometrically.
Ans.
Let the price of a bat and a ball be ₹ x and ₹ y respectively.
According to the question,
3x + 6y = 3900 …(1)
or 3 (x + 2y) = 3900
or x + 2y = 3900/3 =1300 …(2)
Equation (1) represents the total price of 3 bats and 6 balls whereas equation (2) represents the total price of one bat and 2 balls.
To represent these equations graphically, we need at least two solutions for each equation. We write these solutions in table.
3x + 6y = 3900
or y = (3900 – 3x)/6
x  100  300 
y  600  500 
(i)
Also,
x + 2y =1300
or y = (1300 – x)/2
x  500  900 
y  400  200 
(ii)
The below given graphical representation shows that
graphs of both the equations coincide.
Q.3 The cost of 2 kg of apples and 1 kg of grapes on a day was found to be ₹ 160. After a month, the cost of 4 kg of apples and 2 kg of grapes is ₹ 300. Represent the situation algebraically and geometrically.
Ans.
Let the price of 1 kg of apple and 1 kg of grapes be ₹ x and ₹ y respectively.
According to the question,
2x + y = 160 …(1)
And
4x + 2y = 300
or 2x + y = 150 …(2)
Equations (1) and (2) represent the given situation algebraically.
To represent the given situation graphically, we need at least two solutions for each equation. We write these solutions in table.
2x + y = 160 …(1)
or y = 160 – 2x
x  60  40 
y = 160 – 2x  40  80 
(i)
Also,
2x + y = 150 …(2)
or y = 150 – 2x
x  60  40 
y = 150 – 2x  30  70 
(ii)
The graphical representation of the situation is given below. The two lines never intersect each other, i.e., the two lines are parallel.
