Question

The cost of a notebook is twice the cost of a pen. Write a linear equation in two variables to represent this statement

• A. x = 2 y
• B. x - 2y = 0
• C. 2y - x = 0
• D. 3y = 2 x

Answer 1

Answer: (A), (B), (C)

The correct options are
A x = 2 y
B x - 2y = 0
C 2y - x = 0

Let the cost of notebook and pen be x and y

Now, the cost of a notebook is twice the cost of pen
$\therefore$ x = 2 y or x - 2y = 0 or 2y - x = 0
