$\qquad\qquad\huge\underline{\boxed{\sf Answer}}$

Let's plug in the value of x as 7, to check if 7 is the solution to given equation ~

$\qquad \sf  \dashrightarrow \: - 7(x + 5) = - 14$

$\qquad \sf  \dashrightarrow \: - 7(7 + 5) = - 14$

$\qquad \sf  \dashrightarrow \: - 7(12) = - 14$

$\qquad \sf  \dashrightarrow \: - 84 \: \cancel= - 14$

Since, the terms on both sides aren't equal. therefore we can say that 7 isn't the solution ~
