Changing the Subject (pre-GCSE)

(Based on the Tiffin Year 8 scheme of work) (a) Change the subject of any formula where the new subject appears only once. Includes roots, squares, brackets, where x appears within a negative term and/or in the denominator. (b) Be able to cross multiply. (c) Determine a value when the formula and values of all other variables are given.
