Question

Which equation could be used to solve this problem?

Answer 1

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.
