Question: 183

7. If |x + 2| = 3, then x is equal to

A. -5 only
B. 1 only
C. 1 and 5
D. 1 and -5
E. 5 and -5

Correct Answer: D

Explanation:

D. Remember that the absolute value symbol turns everything inside into a positive number, so you know that x + 2 equals 3 or -3. Now you can solve both equations. The first equation, x + 2 = 3, results in x = 1, and the second, x + 2 = -3, results in x = -5. Choice (D) is the only option that includes both of these answers.
