Answer is c
Reason:
It’s not telling the exact number so you put x for it as a variable. It’s asking to divide FIRST and then add. That number divided by 2 would be x/2 and because you are later adding 3 you put (x/2) + 3. Now the last piece of information is that it will equal 8 so at the end of the equation you put =8 so that will create (x/2)+3=8. Out of topic a possible answer will be 10=x
