Question

the cost of pen is 4 times the cost of pencil write a linear equation in two variables to represent statement

Answer 1

Let the cost of pen be Rs.y and that of pencil be Rs.x.
A.T.Q.
4x = y.

Answer 2

Answer:

$y=4x$

Step-by-step explanation:

Given : the cost of pen is 4 times the cost of pencil

To Find: write a linear equation in two variables to represent statement

Solution:

Let the cost of 1 pencil be x

Let cost of pen be y

We are given that the cost of pen is 4 times the cost of pencil

So, cost of pen = 4x

⇒$y=4x$

Hence a linear equation in two variables to represent statement is $y=4x$.
