**Answer:**

There are 20 items on one grocery list and 13 items on second grocery list.

**Step-by-step explanation:**

We are **given** that there are two grocery list and one of the grocery list have seven things less than the other grocery list.

Let** x be the number of items on one grocery list**.

Then, by the given information, there are x -7 items on the second grocery list.

The** total number of items on both the list are 33**.

Then, according to the question,

[tex]x + (x-7) = 33\\2x - 7 = 33\\2x = 40\\x = 20[/tex]

Thus, there are 20 items on one grocery list and (20 -7) = 13 items on second grocery list.
