I believe your answer is:

17

Here’s why:

⸻⸻⸻⸻

`\boxed{\text{Solving for 'x'...}}\\\\2x + 12 = 3x - 5\\--------------\\\rightarrow 2x + 12 - 12 = 3x - 5 - 12\\\\\rightarrow 2x = 3x -17 \\\\\rightarrow2x -3x = 3x-3x - 17\\\\\rightarrow -x = - 17\\\\\rightarrow (-x=-17)/(-1) \\\\\rightarrow \boxed{x = 17}`

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