Answer
$n=\dfrac{m+5x-19}{5}$
Work Step by Step
Using the properties of equality, in terms of $
n
$, the given equation, $
m=19-5(x-n)
$, is equivalent to
\begin{array}{l}
m=19-5x+5n
\\\\
-5n=19-5x-m
\\\\
n=\dfrac{19-5x-m}{-5}
\\\\
n=-\dfrac{19-5x-m}{5}
\\\\
n=\dfrac{-19+5x+m}{5}
\\\\
n=\dfrac{m+5x-19}{5}
.\end{array}
