I'm supposing those is equal to zero.
First distribute the 7.
Then combine the like terms.
Then get x by itself by adding the 15 (The combination of -7 and -8) to both sides.
Finally divide both sides by the coefficient of x,
18.

<h2>The required "option D. 9.6" is correct.</h2>

Step-by-step explanation:

In given figure,

AD = x, DB = 12, BE = 8 and EC = 10

To find, the value of x = ?

Use the Side-Splitting Theorem,

We know that,

$\dfrac{AD}{DB} =\dfrac{BE}{EC}$

⇒ $\dfrac{x}{12} =\dfrac{8}{10}$

⇒ x = $\dfrac{8 \times 12}{10}$

⇒ x = $\dfrac{96}{10}$

⇒ x = 9.6

∴ The value of x = 9.6

Thus, the required "option D. 9.6" is correct.
