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

The video tutorial explains how to solve an equation by balancing both sides, first subtracting 7 from each side to simplify the equation to 3X = -6, and then dividing by 3 to find X = -2. It also covers calculating the expression 3F - 2G by substituting given values for F and G, resulting in a final answer of 8. Marks are awarded for correct methods and final answers.
