Answer:

C. -7 < x < 7

Step-by-step explanation:

|2x| is the absolute value of 2x.  You can think of it as the positive of a number, or as the distance between a number and 0 on a number line.

So |2x| < 14 means 2x is less than 14 units away from 0.

We can split this into two inequalities.

2x < 14 and 2x > -14

Solving both, we get:

x < 7 and x > -7

-7 < x < 7
