Explanation:

$\frac{7}{x + 3} \text{ is already in simplest form}$

$\text{the denominator cannot equal zero as this would make}$
$\text{the expression undefined. Equating the denominator to}$
$\text{zero and solving gives the value that x cannot be}$

$\text{solve "x+3=0rArrx=-3larrcolor(red)" excluded value}$
