1. The problem is to solve a math question suitable for grade 8 students. Since no specific problem was given, let's consider a simple algebraic equation to solve: $2x + 3 = 11$. 2. The formula or rule we use here is to isolate the variable $x$ by performing inverse operations. We want to get $x$ alone on one side of the equation. 3. First, subtract 3 from both sides to cancel the +3 on the left: $$2x + 3 - 3 = 11 - 3$$ which simplifies to $$2x = 8$$ 4. Next, divide both sides by 2 to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{8}{2}$$ which simplifies to $$x = 4$$ 5. So the solution is $x = 4$. This means if you substitute 4 back into the original equation, it will make the equation true. 6. To check: $$2(4) + 3 = 8 + 3 = 11$$ which matches the right side. This is how you solve a simple linear equation step-by-step.
