Question

The cost of a pencil is Rs. 5 less than half of the cost of a ball pen. Write this statement as a linear equation in two variables​

Answer 1

Answer:

x-2y = 10

Step-by-step explanation:

let cost of pen = x

let cost of pencil = y

then ATQ,

y = x/2-5

y = (x-10)/2

2y = x-10

x-2y = 10
