Answer
a solution
Work Step by Step
Substituting $
n=-20$ to the given equation, $
4-\dfrac{1}{5}n=8
$, then
\begin{array}{l}
4-\dfrac{1}{5}(-20)=8
\\\\
4-(-4)=8
\\\\
4+4=8
\\\\
8=8
\text{ (TRUE)}
.\end{array}
Since the solution above ended with a $\text{
TRUE
}$ statement, then the given value of the variable is $\text{
a solution
}$ to the given equation.
