In this lesson
In this video you'll learn about solving linear equations by balancing for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to solve a linear equation with the unknown on one or both sides, including one with a fractional coefficient, by applying the same operation to both sides.

For teachers
This GCSE Maths lesson teaches solving linear equations by balancing. By the end, students should be able to solve a linear equation with the unknown on one or both sides, including one with a fractional coefficient, by applying the same operation to both sides. It works through two worked examples and the mistakes examiners report.
