1. The problem is to solve question 8 again, but since the original question 8 is not provided, I will assume a typical algebraic problem to demonstrate the solution process. 2. Let's consider a common algebra problem: Solve for $x$ in the equation $$2x + 3 = 11$$. 3. The formula used here is to isolate $x$ by performing inverse operations. 4. Step 1: Subtract 3 from both sides: $$2x + 3 - 3 = 11 - 3$$ $$2x = 8$$ 5. Step 2: Divide both sides by 2 to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ $$x = 4$$ 6. Therefore, the solution to the equation is $x = 4$. This process shows how to isolate the variable step-by-step using inverse operations.
