Question

The cost of 5 pens is equals to the cost of two ball pen write the linear equations in two variables to represent the statement.

Answer 1

Answer:

5x-2y = 0

Step-by-step explanation:

Let, the cost of one pen be ‘x’

now, cost of 5 pens = 5×x = 5x

let, the cost of one ball pen be ‘y’

now, the cost of two pens = 2×y = 2y

given that, cost of 5 pens = the cost of two ball pens

⇒ 5x = 2y

⇒ 5x-2y = 0

∴ the linear equation in two variables for the given data is 5x-2y = 0.
