1. The problem is to find the "Different answer" which is ambiguous, so we interpret it as solving a simple algebraic problem or equation. 2. Since no specific equation or problem is given, let's consider a basic example: Solve for $x$ in the equation $2x + 3 = 7$. 3. The formula used is to isolate $x$ by performing inverse operations. 4. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$ 5. Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ which simplifies to $$x = 2$$ 6. Therefore, the solution is $x = 2$. This is a simple example of solving a linear equation by isolating the variable step-by-step.
