Simultaneous means at the same time. Simultaneous equations have the same value of each unknown for all the equations. So all the x s in every equation are worth the same amount. All the y s for every equation are worth the same amount and so on.

When we have two unknowns, we need two equations to work them out. If we have three unknowns, we need three equations and so the list goes on. At GCSE level, you will need to know how to deal with two unknowns at Foundation level and three at Higher level.
