take cost of pen as y, not 2y.
(y x 2 because it is twice of the notebook)
what is y?
The cost of the pen = "y"
but you have written cost of pen = 2y
o ya right..that has to be ;-
cost of notebook=2 x cost of pen(y)
,,x=2y
=> x - 2y = 0

cost of notebook=2 x cost of pen(y)
,,x=2y
=> x - 2y = 0
is this right answer!! ;D
