Answer:
x-2y= 0
Step-by-step explanation:
The cost of a notebook is twice the cost of a pen. ∴, x-2y= 0 is the linear equation in two variables to represent the statement 'The cost of a notebook is twice the cost of a pen'.
Answer:
x – 2y = 0
Step-by-step explanation:
Let’s take the cost of a notebook as Rs. x and the cost of a pen as Rs. y.
Given that cost of a notebook (x) is twice the cost of a pen(y).
So, x = 2y
x – 2y = 0
x – 2y = 0 is the linear equation in two variables that represent the statement.
