Hi there!

I believe your answer is:
[tex]\frac{1}{2}x+7[/tex]

Here’s why:
⸻⸻⸻⸻
[tex]\boxed{\text{Simplifying the equation...}}\\\\\frac{1}{2}(x+14)\\------------\\\rightarrow \frac{1}{2}*x = \frac{1}{2}x\\\\\rightarrow\frac{1}{2}*14=7\\\\\rightarrow \frac{1}{2}(x+14)= \boxed{\frac{1}{2}x+7}[/tex]

Hope this helps you. I apologize if it’s incorrect.
