In this lesson
In this video you'll learn about solving linear equations with brackets for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to solve a linear equation that requires expanding one or more brackets first, by multiplying every term inside each bracket before balancing.
What it covers
- 0:42 What a bracket means + checkable question
- 2:25 Worked example
- 4:25 The minus-sign trap
- 6:51 Exam technique
- 8:42 Your turn now, with one equation and no help from me
- 11:06 What's next

For teachers
This GCSE Maths lesson teaches solving linear equations with brackets. By the end, students should be able to solve a linear equation that requires expanding one or more brackets first, by multiplying every term inside each bracket before balancing. It works through two worked examples and the mistakes examiners report.
