1. The problem is to create a basic knowledge question based on the given syllabus. 2. Since no specific syllabus details were provided, a general example question for basic knowledge in mathematics could be: **Question:** What is the value of $x$ if $2x + 3 = 7$? 3. The formula used here is to solve a simple linear equation: $$2x + 3 = 7$$ 4. To solve for $x$, subtract 3 from both sides: $$2x = 7 - 3$$ $$2x = 4$$ 5. Then divide both sides by 2: $$x = \frac{4}{2}$$ $$x = 2$$ 6. Therefore, the value of $x$ is 2. This question tests basic algebra skills such as solving linear equations.
