Answer: The correct answer is B) division.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

3(x + 4) = 18 (Given)  

3x + 12 = 18 (Distributive Property)  

3x = 6 (Subtraction)  

x = 2

To obtain the result, in the last step we have to divide both sides by 3.

Mathematically speaking:

3x÷3 = 6÷3

x =2

So, the correct answer is B) division.
