Answer

$n=\dfrac{13}{2}$

Work Step by Step

Using the properties of equality, the value of the variable that satisfies the given equation, $ -26=-4n ,$ is \begin{array}{l}\require{cancel} \dfrac{-26}{-4}=n \\\\ \dfrac{\cancel{-2}\cdot13}{\cancel{-2}\cdot2}=n \\\\ \dfrac{13}{2}=n \\\\ n=\dfrac{13}{2} .\end{array}
