Linear Simultaneous EquationsCheatsheet
The whole topic on a page or two, for the night before.
A complete 20-page IGCSE guide to linear simultaneous equations. It covers the substitution, elimination and graphical methods, with clear guidance on which to choose. It then works through harder exam-style questions that need rearranging first or involve fractions. A full section covers forming and solving equations from word problems on prices, ages, perimeters and speeds. The notes also explain the special cases of no solution and infinitely many solutions. Every method comes with step-by-step worked examples, an answer check and common mistakes to avoid. It ends with a summary, a quick-reference guide and exam tips.
