Question

The cost of pen is thrice the cost of pencil. Write a linear equation in two variables to represent this statement.​

Answer 1

Step-by-step explanation:

hey buddy!

heres your answer

let the cost of pencil be x

let the cost of pen be y

now, according to the question cost of pen is 3 times pencil so 3x

now we have an equation

cost of pen is y

cost of pen is 3x

so we can say that $y=3x$

there you have the equation

PLEASE MARK BRAINLIEST IF IT HELPED!!!

Answer 2

The linear equation in two variables to represent the statement is $y-3x=0$.

Given,

The cost of a pen is thrice the cost of a pencil.

To Find,

A linear equation in two variables to represent the given statement.

Solution,

The method of finding a linear equation to imply the given condition is as follows -

Let the cost of a pencil be x Rs. and the cost of a pen be y Rs.

It is given that the price of a pen is equal to 3 times the price of a pencil.

So, 3 times the price of a pencil is 3x. So, 3x is equal to the price of a single pen.

So the linear equation to represent the statement will be $y=3x$

⇒  $y-3x=0$

Hence, the linear equation in two variables to represent the statement is $y-3x=0$.
