Hello there! I can help you! The absolute value symbols make the answer to the expression between the lines positive. Because of this, let's solve as two separate equations: k + 7 = 3, and k + 7 = -3. Let's start with the first one. 3 - 7 is -4. k = -4. Now to the second one. -3 - 7 is -10. Keep in mind that -10 works, because although the sum is -10 and 7 is -3, the sum has an absolute value of 3. There. k = -10 or - 4. The answer is D.
