Simultaneous equations like π = 2π - 1 and π = π + 1 can be represented graphically. To solve the equations graphically, the two lines π = π + 1 and π = 2π - 1 are drawn on the same diagram.
Be careful to note what a GCSE question is asking. If it states βsolve algebraicallyβ then you must do so. To find solutions from graphs, look for the point where the two graphs cross one another.
