To solve the equation 7n + 18 = 45, the first step is to isolate the term containing n. This is done by subtracting 18 from both sides of the equation. By carrying out that subtraction, the equation simplifies to 7n = 45 - 18, which further reduces to 7n = 27.

Next, to solve for n, you need to divide both sides of the equation by 7. This gives n = 27 / 7. When performing the division, you get n = 3.857142..., which can be rounded to 3.857 when expressed as a decimal.

Therefore, the value of n in this equation is accurately represented by the option that corresponds to approximately 3.857, making it the correct answer.
