Step-by-step explanation:
The given expression is
![8-[x-(5+x)]](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8qqpmllrjxp5lyspnqifd7u58se1a1jz9m.png)
We need to simplify the expression.
Let us simplify the expression using the PEMDAS rule.
Thus, removing the parenthesis, we get,
![8-[x-5-x]](https://img.qammunity.org/2021/formulas/mathematics/middle-school/n2pd4dlxr82pj77a0s3lvo2jmbndvcyqwu.png)
Adding the terms within the parenthesis, we have,

Simplifying the terms, we have,

Finally, adding the terms, we have,
13
Thus, the solution of the expression is 13
Hence, Option D is the correct answer.
