This is another video in the Further Maths Units 3 and 4 series looking at straight lines. In previous years you will have looked at how to solve simultaneous equations using substitution and elimination methods. I look at using the CAS to solve simultaneous equations by drawing them on the graphical screen and using the system of equations function. There are a number of worked examples with clear instructions on how to use the CAS all backed by clearly explained theory. The final section of the video looks at how to solve using the substitution and elimination methods.
