Answer 1

Option B) x = 27

Explanation:

To solve for 'x' we would have to do inverse operations.

================================================

`18 = x - 9\\\rule{150}{0.5}\\x - 9 = 18 \leftarrow \text{Switched Sides}\\\\x - 9 + 9 = 18 + 9\\\\\boxed{x= 27}`

================================================

Hope this helps.
