What about this? I get: Multiply by 18 but the answer is I know I'm missing something again...

On removing the parentheses enclosing the second term, you should have applied the preceding minus sign to both of the terms within the parentheses, not just the first. Then you multiplied by 18 . . . if you do that, you need to divide by 18 as well. Towards the end, you omitted an "x" from your work, but carried on as though it were present.
