These simultaneous equations are split into four groups: (1) no multiplication required to eliminate x or y, (2) multiplication of only one equation needed, (3) multiplication of both equations required and (4) a mixed set of equations. Remember to number the equations and make a note of what you plan to do at each stage of the calculation. This will help to prevent mistakes.
