text: Simultaneous equations are a system of 2 equations, with 2 variables (i.e. letters) that have to be solved at the same time, or simultaneously. Whilst they might sound a bit scary, once you learn the process and apply common sense to your workings you will have them sorted in no time. See how well you get on in this GCSE Maths quiz!
  You should be able to recognise a problem that is based on simultaneous equations – it will have two equations, and include two different variables. Once you spot this you need to decide which method will be the easier to use.
