What is the solution to the equation 3(x - 4) = 12?

To solve the equation 3(x - 4) = 12, you start by isolating the term inside the parentheses. Begin by dividing both sides of the equation by 3, which gives you:

x - 4 = 4.

Next, add 4 to both sides to solve for x:

x = 4 + 4.

This simplifies to x = 8.

Therefore, the solution to the equation is 8. This means that when you substitute 8 back into the original equation, both sides will equal, confirming that x = 8 is indeed correct.
