2 |4x| - 8 = 16
8x - 8 = 16
8x - 8 + 8 - 16 + 8
8x = 24
8x/8 = 24/8 = 3
2 (4*3) - 8 = 16
2 (12) - 8 = 16
24 - 8 = 16
16 = 16

In mathematics, the absolute value (or modulus) | a | of a real number a is the numerical value of a without regard to its sign. So, for example, the absolute value of 3 is 3, and the absolute value of –3 is also 3. The absolute value of a number may be thought of as its distance from zero. (Wikipedia)

P.S. How do you type the absolute value bars?
