1. The problem is to provide a grade 7 level answer, so I will explain a simple algebra problem step-by-step. 2. Let's solve the equation $2x + 3 = 11$. 3. The goal is to find the value of $x$ that makes the equation true. 4. First, subtract 3 from both sides to isolate the term with $x$: $$2x + 3 - 3 = 11 - 3$$ which simplifies to $$2x = 8$$ 5. Next, 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 is $x = 4$. 7. This means if you replace $x$ with 4 in the original equation, both sides will be equal. Final answer: $x = 4$
