First Day:

X-pencils sold.
2X-notebooks sold.

Second Day:

2X-pencils sold.
3X-notebooks sold.

First Day:

X + 2X = 18 Pencils
X = 6 Pencils.

2x + 3x = 30 Notebooks
X = 6 Notebooks

First Day:
X = 6 Pencils sold.
2x = 2*6 = 12 Notebooks sold.

Second Day:
2x = 2*6 = 12 Pencils sold.
3x = 3*6 = 18 Notebooks.
