Linear Simultaneous Equations - Substitution Method | GCSE Maths Pro

Описание: In this video we go through the first part of simultaneous equations which focuses on solving LINEAR simultaneous equations. In particular we look at using the substitution method. Solving linear simultaneous equations is for BOTH foundation and higher tier students. You can choose between using the substitution method demonstrated in this video or the elimination method demonstrated in the previous video. Make sure you are happy with solving equations and finding the lowest common multiple before attempting this topic.
