y=½ x - 5

Step-by-step explanation:

Given : The cost of a ball pen is Rs.5 less than half of the cost of fountain pen.

To Find: write this statement as a linear equations in two variables.

Solution:

Let the cost of notebook be x

Let the cost of pen be y

Now we are given that the cost of a pen is Rs.5 less than half of the cost of notebook

So, A.T.Q

y=½ x - 5

Hence the given statement as a linear equations in two variables is

y=½ x - 5
