Unformatted text preview: Since 5 − x  gives the distance from x to 5, the question says that the distance from x to 5 must be less than 6. So, find all numbers x whose distance from 5 is less than 6. We indicate the set of all numbers within a distance 6 of 5 in the figure below. 6 6 5 − 6 = −1 5 5 + 6 = 11 You can now read the solution directly from the figure: −1 < x < 11, or in interval notation (−1, 11). Correct answer is: ( − 1, 11)...
