The solution to the equation x + 8 = -2 involves isolating the variable x. Here's how you can solve it step by step:
1. Start with the equation x + 8 = -2.
2. To isolate x, you need to get rid of the constant term 8 on the left side. You can do this by subtracting 8 from both sides of the equation.
3. x + 8 - 8 = -2 - 8
4. x = -10
Therefore, the solution to the equation x + 8 = -2 is x = -10, which means that when you substitute x with -10 in the equation, it will satisfy the equation x + 8 = -2. So, the correct answer is:
○ B. x = -10
