Answer 1

Answer:

$\boxed{C. \: x = 2}$

Step-by-step explanation:

$= > Solve \: for \: x \: over \: the \: integers: \\ 3 |x - 6| = 12 \\ \\ = > Divide \: both \: sides \: by \: 3: \\ |x - 6| = 4 \\ \\ = > Split \: the \: equation \: into \: two \: possible \: cases: \\ x - 6 = 4 \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: x - 6 = -4 \\ \\ = > Add \: 6 \: to \: both \: sides: \\ x = 10 \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: x = 2 \\ \\ Answer: x = 10 \: \: \: \: \: \: \: \: or \: \: \: \: \: \: \: \: x = 2$
