Example Question #11 : Working With Inequalities And Absolute Value
Which of the following is not a possible value for x given the inequality above?
Possible Answers:
15
25
24
12
Correct answer:
12
Explanation:
In order to simplify this inequality, we'll want to start by subtracting 12 from both sides to arrive at
if we then multiply both sides of the inequality by 4 to cancel the coefficient in front of x, we get to
Thus, 12 is not a possible value of x given the simplified inequality.
Note - we could also solve this question by plugging each option in for x, but this route is likely somewhat more time consuming, so stay flexible in your approach on a question-to-question basis!
