Following on from a previous video where I looked at setting up linear equations in one unknown, I am back and throwing in another unknown. Worry not! This video (which is a part of the VCE General Maths course on Linear Equations and Relations) is everything you need to smash your understanding to the next level. I look at an example of how to extra information from a question and how to use it to construct and equation. I then go on and solve the equation. All of this is done with my unique and easy to understand style.
