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

The video tutorial covers solving algebraic equations. Part A involves solving X + X + X = 51, resulting in X = 17. Part B addresses y / 4 = 3, leading to y = 12. Part C solves 2F + 7 = 18, with F = 11/2. The tutorial concludes with a recap and tips on rearranging equations to isolate the unknown variable.
