Answer
$\color{blue}{-3}$
Work Step by Step
The rational expressions have the same denominator so they are similar.
Subtract the numerators and copy the denominator to obtain:
$=\dfrac{(m+7)-(4m+22)}{m+5}$
Subtract each term of the subtrahend to obtain:
$=\dfrac{m+7-4m-22}{m+5}
\\=\dfrac{-3m-15}{m+5}$
Factor out $-3$ in the numerator to obtain:
$\\=\dfrac{-3(m+5)}{m+5}$
Cancel the common factors to obtain:
$\\=\color{blue}{-3}$
