To solve this problem, we need to determine the value of x, which represents the number of friends Jean has.
We know that Jean and her friends will each receive 7 dominoes. Therefore, the total number of dominoes distributed is 7(x + 1), where x represents the number of friends Jean has and 1 represents Jean.
The total number of dominoes in the set is 28.
We can set up the equation as follows:
Total number of dominoes distributed = Total number of dominoes in the set
7(x + 1) = 28
Let's simplify and solve for x:
7x + 7 = 28
To isolate x, we subtract 7 from both sides of the equation:
7x + 7 - 7 = 28 - 7
7x = 21
To solve for x, we divide both sides of the equation by 7:
x = 21 / 7
x = 3
The value of x is 3. Jean has 3 friends.
#### 3
The answer is: 3
