w +7 = 357 What value of w is the solution to the given equation?
Correct answer: B (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice B is correct. Subtracting 7 from each side of the given equation yields =350 w . 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 =357 +7=357 w , not w . Choice C is incorrect. This is the value of w that is the -7=357 +7=357 solution to the equation w , not w . Choice D is incorrect and may result from conceptual or calculation errors.
