To solve this problem, we need to determine the value of x, which represents the number of additional cards that Aubrey added to the deck.
We know that the initial deck has 52 cards and after adding x cards, it is split evenly among three players, with each player having 18 cards.
Let's set up the equation to represent this:
Number of initial cards + Number of additional cards = Total number of cards
52 + x = 3 * 18
Let's simplify and solve for x:
52 + x = 54
To isolate x, we subtract 52 from both sides of the equation:
52 + x - 52 = 54 - 52
x = 2
The value of x is 2.
#### 2
The answer is: 2
