Given : The cost of a notebook is Rs 6 more than twice the cost of a pen
6time the cost of the pen is equal to 3times the cost of the notebook.
To Find : Represent the situation graphically
Solution:
cost of pen = x
cost of note book = y
cost of a notebook is Rs 6 more than twice the cost of a pen
=> y = 2x + 6
6time the cost of the pen is equal to 3times the cost of the notebook.
=> 3y = 6x
These are parallel lines
No common solutions
Lines are parallel hence no solution
