Oct 16th, 2015

Thank you for the opportunity to help you with your question!

2|3x-16| means that the we need to take the absolute value of 3x-16 and then multiply by 2. 

The absolute value is always zero or a positive number, thus we should the negative sign for the answer if any.

Thus If x=4, then 2|3(4)-16|  = 2|-4| = 2*4 = 8

Thus, for x =4, then the solution to the equation is 8.

Please let me know if you need any clarification. I'm always happy to answer your questions.
