GCSE Secondary Maths Age 13-17 - Algebra: Algebra - Explained

The video tutorial addresses an algebra problem involving three schools sending students to a revision day. Redlands School sends X students, St Samuel's sends twice as many, and Francis Long sends 7 fewer than Redlands. Each student pays £15, totaling £1155. The task is to determine the number of students each school sent. The solution involves setting up and solving equations, leading to the conclusion that Redlands sent 21 students, St Samuel's 42, and Francis Long 14. The video also explains the marks allocation for the problem.
