3 Minute Math - Solving linear equations with brackets on both sides

From a channel Lumen includes in full: This is a veteran maths tutor's channel of short, worked exam-style examples covering primary arithmetic through GCSE and A-level integration. Every transcript shows plain step-by-step teaching with no hooks or hype (algebraic proof, subtraction methods, ratio, circle/line intersection). The titles are descriptive throughout. The only off-topic upload, the early 'walk through paper' craft video, is caught by a title pattern.
