x + 45 = 48 What is the positive solution to the given equation?

Question

Accepted Answer

Choice A is correct. The given absolute value equation can be rewritten as two linear equations: x + 45 = 48 and - x + 45 = 48 , or x + 45 = - 48 . Subtracting 45 from both sides of the equation x + 45 = 48 yields x = 3 . Subtracting 45 from both sides of the equation x + 45 = - 48 yields x = - 93 . Thus, the given equation has two possible solutions, 3 and - 93 . Therefore, the positive solution to the given equation is 3 . Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
