1. The problem is to explain a math concept suitable for a 14-year-old level. 2. Since no specific problem was given, I will provide a simple algebra example: solving the equation $2x + 3 = 11$. 3. The formula used is to isolate the variable $x$ by performing inverse operations. 4. Step 1: Subtract 3 from both sides to get rid of the constant term on the left: $$2x + 3 - 3 = 11 - 3$$ which simplifies to $$2x = 8$$ 5. Step 2: Divide both sides by 2 to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ which simplifies to $$x = 4$$ 6. So, the solution to the equation $2x + 3 = 11$ is $x = 4$. 7. This means if you replace $x$ with 4 in the original equation, both sides will be equal. This explanation uses simple steps and clear language to help a 14-year-old understand solving a basic linear equation.
