1. The problem is to solve number 6, but since no specific problem statement was given, I will assume you want a general example of solving a typical algebraic problem. 2. Let's consider the 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: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ $$x = 4$$ 6. Therefore, the solution is $x = 4$. This is a simple linear equation solving process where you undo addition and multiplication to isolate the variable.
