1. Let's start by understanding the problem you want to solve. Since you asked for the whole pattern of solving step by step, I will demonstrate a general approach to solving algebraic equations. 2. The general formula or rule for solving an equation like $ax + b = 0$ is to isolate the variable $x$ by performing inverse operations. 3. Step 1: Subtract $b$ from both sides to get $ax = -b$. 4. Step 2: Divide both sides by $a$ to isolate $x$, so $x = \frac{-b}{a}$. 5. This is the solution for a linear equation. The key rules are to perform the same operation on both sides and to reverse operations in the order opposite to how they were applied. 6. If you have a specific equation or problem, please provide it, and I will show the detailed step-by-step solution.
