Answer:
x = -14
Step-by-step explanation:
The expression to write in this problem is:
"the sum of x and 12 equals the sum of half of x and 5"
We have:
- The sum of x and 12 is: 
- The sum of half of x and 5 is: 
So, the equation to write in this problem is

We solve it as follows:
1) First, we subtract
from both sides, and we get

2) Then, we subtract 12 from both sides:

3) Now we multiply both sides by 2:

So, this is the solution.
