1. Let's start by understanding that you asked for a clear explanation to help you understand a math problem. 2. Since you did not specify a particular problem, I will explain a common algebra concept: solving a linear equation. 3. A linear equation looks like this: $ax + b = 0$, where $a$ and $b$ are constants and $x$ is the variable. 4. The goal is to find the value of $x$ that makes the equation true. 5. To solve for $x$, we use the formula: $$x = -\frac{b}{a}$$ 6. Important rules: - $a$ cannot be zero because division by zero is undefined. - You can add, subtract, multiply, or divide both sides of the equation by the same nonzero number without changing the solution. 7. Example: Solve $3x + 6 = 0$. 8. Subtract 6 from both sides: $3x = -6$. 9. Divide both sides by 3: $x = -\frac{6}{3} = -2$. 10. So, the solution is $x = -2$. 11. This means when $x$ is $-2$, the equation $3x + 6 = 0$ holds true. 12. If you have a specific problem, please share it, and I will explain it step-by-step!
