This video covers how to solve simultaneous equations. This is where you have two equations that both have 2 unknown variables, like the equations 2a + b = 5 and 3a + 2b = 9. The only way to solve these and find the missing variables (a and b in this case) is solve both equations simultaneously.
This video is suitable for maths courses around the world.
