Answer:
x=30
Step-by-step explanation:
Please note, that you have a flowchart helping you solve the task - the answer to "how to solve this quesiton" is literally given below the question.
They say that if you first divide x by 2, then add 8, you get 23.
That means that (going backwards) if you start with 23 and subtract 8, then multiply by 2, you get x.
23-8 = 15
15 * 2 = 30
x = 30.
