1. The problem is to find an easy solution suitable for grade 8 level. 2. Since no specific problem is given, let's consider a simple 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. First, subtract 3 from both sides: $$2x + 3 - 3 = 11 - 3$$ which simplifies to $$2x = 8$$. 5. Next, divide both sides by 2 to solve for $x$: $$\frac{2x}{2} = \frac{8}{2}$$ which simplifies to $$x = 4$$. 6. So, the solution is $x = 4$. 7. This method uses basic algebraic principles: whatever you do to one side of the equation, you must do to the other to keep it balanced. 8. This approach is easy and suitable for grade 8 students.
