If X = 4, what is the value of 2│3X – 16│

First, we use the concept of substitution. Since X = 4, take the value 4 and place it where there is X.

2│3*4 – 16│

Second, we use the concept of multiplication and compute the value after replacing X with 4.

3*4 = 12.

Then subtract 16 from 12, │12 -16│= │-4│. Also, it can be written as │4│.

Third, the answer above depicts that, 4 is an absolute number. Therefore, multiply 2 by 4 and get the following answer.

2*4= 8.

The correct answer is 8.
