Question

Answer the following as requested 1."The coast of a note book is twice the cost of a pen" . write a linear equation in two variable to represent this statement​

Answer 1

Answer:

Given that cost of a notebook (x) is twice the cost of a pen(y). So, x = 2y. x – 2y = 0 is the linear equation in two variables that represent the statement.

Answer 2

Answer:y-2x =0 is the linear equation in two variable

Step-by-step explanation:

let the cost of notebook be Rs y

let the cost of pen be Rs x

ATQ

cost of notebook = 2x

y = 2x

y-2x =0
