9(4−3x) +2 = 8(4−3x) +18 If, what is the value 4−3x of? −16
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
4-3 Choice D is correct. The value of x can be found by isolating this expression in the given equation. Subtracting 2 from both sides of the given equation yields 9 4-3 =8 4-3 +16 8 4-3 ^ xh ^ xh . Subtracting ^ xh from both sides of this equation 9 4-3 -8 4-3 =16 1 4-3 =16 4-3 =16 yields ^ xh ^ xh , which gives ^ xh , or x . 4-3 16 Therefore, the value of x is . Choice A is incorrect and may result from conceptual or calculation errors. 4-3 Choice B is incorrect. This is the value of x, not x. Choice C is incorrect and may result from conceptual or calculation errors.
