Question

The cost of a notebook is twice the cost of a pen. Write a linear equation in two
variables to represent this statement.
(Take the cost of a notebook to be
`xand that of a pen to be`y).

Answer 1

Let the price of the pen be \(x\) and the price of the notebook be \(y\). Can you make the equation now?

Answer 2

y=x/2

Answer 3

no :(

Answer 4

Oh, we have the opposite.

Answer 5

Then it is \(y=\dfrac{x}{2}\)

Answer 6

But I'd rather take \(y\) as the price of the notebook.

Answer 7

@ParthKohli what's the difference?

Answer 8

You don't get fractions in \(y=2x\) :-)

Answer 9

lol

Answer 10

I failed in my exam! :-O
