To find the value of x in the equation 3(x - 4) = 12, start by simplifying the equation.

First, divide both sides by 3 to isolate the expression within the parentheses:

x - 4 = 12 / 3

This simplifies to:

x - 4 = 4

Next, to solve for x, add 4 to both sides of the equation:

x = 4 + 4

This results in:

x = 8

Thus, the value of x is 8, confirming that the correct answer is indeed the first option.
