Answer 2

In accordance with the information provided in the question,

We have find the value of the supplied expression in the above question.

Given the data in question 3(n-5)=-21

Arrange the equation $3n-15=-21$

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift 15 from LHS to RHS,

So, we will get it as,

$\Rightarrow 3n-15=-21\\\Rightarrow 3n=-21+15\\\Rightarrow 3n=-6\\\Rightarrow n=\frac{-6}{3} \\\Rightarrow n=-2$

Hence, value of "n" in above equation will be -2.
