The equation representing the problem is 2x + (x - 8) = -16 + x. Simplifying, we get 3x - 8 = -16 + x, which simplifies further to 2x = -8, leading to x = -4. However, there was a mistake in my calculation. Correctly solving, 2x + x - 8 = -16 - x, then 3x - 8 = -16, 3x = 8, x = -8/3, which does not match any of the options provided. The correct approach is: 2x + (x - 8) = -16 - x, simplifying to 3x - 8 = -16 - x, then 4x = -8, leading to x = -2.
