Explanation

Choice B is correct. Subtracting 7 from each side of the given equation yields w = 350 . Therefore, the value of w that is the solution to the given equation is 350 .

Choice A is incorrect. This is the value of w that is the solution to the equation 7 w = 357 , not w + 7 = 357 .

Choice C is incorrect. This is the value of w that is the solution to the equation w - 7 = 357 , not w + 7 = 357 .

Choice D is incorrect and may result from conceptual or calculation errors.
