Step-by-step solution

3 steps

B) 5

Write the given equation.
$3n + 5 = 20$
Subtract 5 from both sides of the equation to isolate the term with $n$ .
$3n + 5 - 5 = 20 - 5$ $3n = 15$
Divide both sides by 3 to solve for $n$ .
$\frac{3n}{3} = \frac{15}{3}$ $n = 5$
The value of $n$ is 5. This corresponds to option B.

The final answer is $\text{B) 5}$ .
