The Corbett Maths solving equations textbook is a structured learning resource designed to help students master algebraic equations through progressive exercises and clear explanations.
The textbook follows a scaffolded approach, starting with basic linear equations and gradually introducing more complex scenarios. Each section includes:
| Equation Type | Example | Page Range |
|---|---|---|
| Linear equations | 3x + 5 = 20 | 12-25 |
| Equations with fractions | (2/3)x + 1 = 5 | 26-38 |
| Quadratic equations | 2x² - 5x + 3 = 0 | 39-52 |
| Simultaneous equations | 2x + y = 8 x - y = 2 |

This textbook is primarily used in UK secondary schools (Key Stage 3 and GCSE level) as both classroom material and independent study resource. Its structured approach makes it particularly effective for:
Many students find the progressive difficulty particularly helpful. As one student noted, "Starting with simple equations gave me confidence before tackling harder problems."
Many students initially confuse solving equations with simplifying expressions. While simplification involves combining like terms, equation solving requires isolating the variable. The textbook addresses this directly in its introductory section.
Another frequent mistake is treating coefficients and variables interchangeably. The textbook's worked examples emphasize the difference between constants (like 5 in 3x + 5) and variables (like x in the same expression).
Consider solving 4(x + 3) = 28:
Step 1: Divide both sides by 4 → x + 3 = 7 Step 2: Subtract 3 from both sides → x = 4
This two-step process appears in the textbook's linear equations section, with similar examples increasing in complexity throughout.
