Solution

The correct option is B $- 3$
Given, $5 x - 2 (6 + 7 x) = 15$
$\Rightarrow 5 x - 12 - 14 x = 15$
Bring $x$ terms on one side and constants on another side.
$5 x - 14 x = 15 + 12$
$\Rightarrow - 9 x = 15 + 12$
$\Rightarrow x = - \frac{27}{9}$
$\Rightarrow x = - 3$
Therefore, $x$ is equal to $- 3$ .
