1. **State the problem:** Solve Question 4 (the exact problem statement is not provided, so we assume it is a typical algebraic or arithmetic problem). 2. **Identify the formula or method:** Since the problem is not specified, we will demonstrate a general approach to solving algebraic equations: isolate the variable by performing inverse operations. 3. **Example problem:** Suppose Question 4 is to solve for $x$ in the equation $$2x + 3 = 11$$. 4. **Step 1: Subtract 3 from both sides** to isolate the term with $x$: $$2x + 3 - 3 = 11 - 3$$ $$2x = 8$$ 5. **Step 2: Divide both sides by 2** to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ $$x = 4$$ 6. **Final answer:** $x = 4$ This method applies to many linear equations: isolate the variable step-by-step using inverse operations such as addition/subtraction and multiplication/division.
