    When doing this kind of question, remember BODMAS or the equivalent that you have learned. It tells you the correct order to work out your equations. Always work out grouped terms first, whether they are grouped by parentheses, radicals or modulation.

    If you have a go, then I can help point to you where you went wrong.
