1. **Stating the problem:** Solve question 5 (assuming it is an algebraic equation or expression to solve). 2. **Formula and rules:** Since the exact problem is not provided, I will demonstrate a general approach to solving an algebraic equation: isolate the variable by performing inverse operations step-by-step. 3. **Intermediate work:** Suppose question 5 is to solve the equation $$2x + 3 = 11$$. 4. Subtract 3 from both sides: $$2x + 3 - 3 = 11 - 3$$ $$2x = 8$$ 5. Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ $$x = 4$$ 6. **Explanation:** We first removed the constant term on the left side by subtracting 3 from both sides to keep the equation balanced. Then, we divided both sides by the coefficient of $x$, which is 2, to isolate $x$. The solution is $x=4$. **Final answer:** $x=4$
