Access NCERT Solutions for Maths Chapter 4 – Linear Equations in Two Variables

The notion of Linear Equations in Two Variables is covered in NCERT Solutions for Class 9 Maths Chapter 4 Exercise 4.1, which is based on the geometrical representation of equations of lines parallel to the x-axes and y-axes. A system of equations of the form ax+by+c=0, where a, b, and c are real integers, is known as Linear Equations in Two Variables. These equations may have a single solution, no solutions, or an infinite number of solutions. Students must first establish the values of the variables before they can identify the set of solutions to the Linear Equations With Two Variables. The NCERT Solutions for Class 9 Maths Chapter 4 Exercise 4.1, dealt with the graphical representation of equations as lines parallel to x-axes and y-axes. A line parallel to the y-axis will have the form x=k, which denotes that any value of y has the same effect on x, and any constant value is used for k. Similar to this, a line parallel to the x-axis will have the form y=k, meaning that the value of y is constant regardless of the values of x and k.

Q.1 The cost of a notebook is twice the cost of a pen. Write a linear equation in two variables to represent this statement.The cost of a notebook is twice the cost of a pen. Write a linear equation in two variables to represent this statement.

Ans
Let the cost of a notebook and a pen be x and y respectively.
Since, cost of a notebook = 2 x cost of a pen
x = 2y or x – 2y = 0
Which is required linear equation.
