Yes, I am sure.

By dividing both sides of the equation 3(x-4)=18 by 3, we get x-4=6.

To solve for x, we need to add 4 to both sides of the equation, resulting in x=10.

So, the correct method would be to first divide by 3, then subtract 4.

Let's analyze each option systematically to determine which method would result in the correct answer.

A. First, distribute the 3, then add 4, and lastly divide by 3.
In this option, you distribute the 3 to both terms inside the parentheses and then proceed to add 4. After that, you divide by 3. However, this sequence of operations is not equivalent to the original problem because it does not follow the same order of operations. Therefore, option A is not the correct method.

B. First, divide by 3, then subtract 4.
In this option, you start by dividing both sides of the equation by 3. Afterward, you subtract 4 from both sides. If we follow this sequence of operations, we would have x - 4 = 6. Then, adding 4 to both sides, we get x = 10. This result satisfies the original equation, so option B is the correct method.

C. First, distribute the 3, then add 12, and lastly divide by 3.
Similar to option A, this method involves distributing the 3 to both terms inside the parentheses. However, instead of adding 4, option C suggests adding 12. Since this is not the correct value, option C is not the correct method.

D. First, multiply by 1/3, then subtract 4.
In this option, you begin by multiplying both sides of the equation by 1/3. Then, you subtract 4 from both sides. Following this sequence of operations, we obtain x - 4 = 6/3. After adding 4 to both sides, we get x = 10/3. This result does not satisfy the original equation, so option D is not the correct method.

Consequently, the correct method that would yield the correct answer for solving the equation 3(x - 4) = 18 is option B: First, divide by 3, then subtract 4.
