Question

The cost of a notebook is twice the cast of a pen . write a linear equationsin two varables to represent this statement. ​

Answer 1

Answer:

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

Given the cost of a notebook is twice the cost of a pen.

Then x=2y

or, x−2y=0.

This is the required linear equation in two variables.

Answer 2

Answer:

write a linear equation in 2 variable to represent the statement . (take the cost of a notebook to be x and that of pen be rs y)
