Option B) x = 27
Step-by-step explanation:
To solve for 'x' we would have to do inverse operations.
================================================
[tex]18 = x - 9\\\rule{150}{0.5}\\x - 9 = 18 \leftarrow \text{Switched Sides}\\\\x - 9 + 9 = 18 + 9\\\\\boxed{x= 27}[/tex]
================================================
Hope this helps.
