OG详解-OG8 数学2 Q16

Choice D is correct. The value of 4-3x can be found by isolating this expression in the given equation. Subtracting 2 from both sides of the given equation yields  9(4-3x)= 8(4-3x)+16. Subtracting 8(4-3x) from both sides of this equation yields 9(4-3x)-8(4-3x)= 16, which gives 1(4-3x)= 16, or 4-3x = 16. Therefore, the value of 4-3x is 16.
Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect. This is the value of x, not 4-3x. Choice C is incorrect and may result from conceptual or calculation errors.
