Thought Process:

1. Goal: Isolate the variable ( x ) on one side of the equation.

2. Step 1: Subtract ( 2x ) from both sides to eliminate ( x ) on the right:

[

3x + 5

]

3. Step 2: Subtract 5 from both sides to isolate ( x ):

[

x + 5

4. Verification: Substitute ( x = -12 ) back into the original equation:

Final Answer:

The solution is (boxed{-12}).
