Solving linear equations and developing formulas | Year 11 General Maths | MaffsGuru.com
**
This is the second video in this series of videos and looks at how we can solve linear equations and develop formula. This video is part of the VCE Units 1 and 2 Year 11 General Maths course. I take a look at how to solve linear equations and how to use unpacking (or back tracking) to find the value of the letters. There are lots of worked examples and each is explained in an easy to understand way.

This maths video has been created for courses which are delivered in Australia but, as Maths is a constant, it is equally helpful for students in the USA, UK and other countries who are looking for good maths videos for both high school and middle school.
