1. The problem is to provide a step-by-step explanation for a math question, but since no specific question was given, I will demonstrate a general approach to solving algebraic equations. 2. A common formula used in algebra is the linear equation formula: $$ax + b = 0$$ where $a$ and $b$ are constants and $x$ is the variable. 3. To solve for $x$, we isolate the variable by performing inverse operations: 4. Subtract $b$ from both sides: $$ax = -b$$ 5. Divide both sides by $a$ (assuming $a \neq 0$): $$x = \frac{-b}{a}$$ 6. This gives the solution for $x$ in terms of $a$ and $b$. 7. This method applies to any linear equation and is fundamental in algebra. Since no specific problem was provided, this general explanation serves as a step-by-step guide to solving linear equations.
