About this lesson
This video, which forms part of the Year 9 Linear and Simultaneous equations part of the course, looks at how we can solve linear equations. I look at how we can use unpacking to find the values of missing letters (pronumerals). There are lots of worked examples where I look at how to unpack (or reverse) the steps needed to find the value of the given letter. I look at examples with negative coefficients and lots of examples with fractions (as I know these can trick lots of people). The theory is explained in an easy to understand way and is mapped against the Cambridge Series of textbooks.
