Which equation could be used to solve this problem?
The number of items on two grocery lists differs by 9. The total number of items for both lists is 33. How many items are on each
List?
X + x = 33
x + (x - 9) = 33
x + (x - 9) = 42
x + (x + 9) = 42

The equation that represents how many items are on each list is option B) x + (x-9) = 33.

Step-by-step explanation:

There are two different lists of grocery.

The number of items in the 1st grocery list = x

The number of items in the 2nd grocery list differs by 9 from the number of items in the 1st grocery list.

Therefore, the number of items in the 2nd grocery list = (x-9)

The total number of items for both lists = 33.

The equation can be formed as :

number of items in the 1st list +  number of items in the 2nd list = total number of items.

⇒ x + (x-9) = 33

The equation that represents how many items are on each list is x + (x-9) = 33.
