Answer 2

Answer:

2x + y = 100

4x + 2y = 200

Step-by-step explanation:

Let the number of pens be x and number of pencils be y

Therefore, now, the number of pens in the first case = 2x and number of pencils = y

Therefore number of pens in the second case = 4x and number of pencils = 2y

Hope this helps
