To solve the given expression [tex]\(8x - x\)[/tex] with [tex]\(x = 2\)[/tex], follow these steps:

1. Substitute the given value of [tex]\(x\)[/tex]: Replace [tex]\(x\)[/tex] with 2 in the expression. The expression becomes:
[tex]\[ 8 \cdot 2 - 2 \][/tex]

2. Calculate the multiplication: Perform the multiplication [tex]\(8 \cdot 2\)[/tex] first.
[tex]\[ 8 \cdot 2 = 16 \][/tex]

3. Subtract [tex]\(x\)[/tex] (which is 2) from the result: Now, subtract 2 from the result of the multiplication:
[tex]\[ 16 - 2 = 14 \][/tex]

Therefore, the value of [tex]\(8x - x\)[/tex] when [tex]\(x = 2\)[/tex] is [tex]\(14\)[/tex]. The correct answer is C 14.
