Solving Equations II – Edexcel GCSE (1MA1): Foundation Tier

About this Course

About the Course

In this course, Professor Keith Ball (University of Warwick) continues his exploration of solving equations, covering Topics A19 and A21 in the Pearson Edexcel GCSE (9-1) Mathematics (1MA1) Specification for Foundation Tier. In the first mini-lecture, we give an introduction to solving simultaneous equations by looking at graphs and thinking about what it means for two equations to hold ‘simultaneously.’ In the second mini-lecture, we show how to solve simultaneous linear equations by substitution (Topic A19) before moving onto solving simultaneous linear equations by cancellation in mini-lecture three (Topic A19). In the fourth and fifth mini-lectures, we look at how mathematical formulae appear in real-world applications and consider speed and distance, cost and rates, and Fahrenheit and Celsius, all of which involve linear or simultaneous equations (Topic A21).
