Question

The cost of pen is 5 rupee less than half the cost of a notebook write this statement as a linear equation in two variable​

Answer 1

Answer:x= 1/2y-5

where y is the price of the book and x is the pen

Step-by-step explanation:

Answer 2

Answer:Let the cost of pen be x and the cost of a notebook be y.

Now,

Cost of notebook = y

Since cost of a notebook is 5 rupees less than half the cost of a notebook then we have

x = (y/2) - 5

Multiplying both sides by 2 , we get

2x= y - 10

Therefore the required linear equation in two variable is

2x-y+10 = 0
