1. The problem is to solve the equations given. Since no specific equations are provided, I will demonstrate how to solve a general linear equation as an example. 2. Consider the equation $ax + b = 0$, where $a$ and $b$ are constants and $a \neq 0$. 3. The formula to solve for $x$ is derived by isolating $x$: $$ax + b = 0 \implies ax = -b \implies x = \frac{-b}{a}$$ 4. Important rules: - Division by zero is undefined, so $a$ must not be zero. - The solution is unique for linear equations. 5. Example: Solve $3x + 6 = 0$. - Subtract 6 from both sides: $3x = -6$ - Divide both sides by 3: $x = \frac{-6}{3} = -2$ 6. Therefore, the solution to the equation $3x + 6 = 0$ is $x = -2$. If you provide a specific equation, I can solve that exactly.
