Answer: $x=\bold{\dfrac{a(c-2)}{9+b}}$

Step-by-step explanation:

9x + 2a = ac - bx

9x = ac - bx - 2a subtracted 2a from both sides

9x + bx = ac - 2a added bx to both sides

x(9 + b) = a(c - 2) factored out x from the left and a from the right

$x=\large\boxed{\dfrac{a(c-2)}{9+b}}\\$ divided both sides by 9+b

The bearing of the plane is approximately 178.037°. $\blacksquare$

<h3>Procedure - Determination of the bearing of the plane</h3><h3 />

Let suppose that bearing angles are in the following standard position, whose vector formula is:

$\vec r = r\cdot (\sin \theta, \cos \theta)$ (1)

Where:

$r$ - Magnitude of the vector, in miles per hour.
$\theta$ - Direction of the vector, in degrees.

That is, the line of reference is the $+y$ semiaxis.

The resulting vector ( $\vec v$ ), in miles per hour, is the sum of airspeed of the airplane ( $\vec v_{A}$ ), in miles per hour, and the speed of the wind ( $\vec v_{W}$ ), in miles per hour, that is:

$\vec v = \vec v_{A} + \vec v_{W}$ (2)

If we know that $v_{A} = 239\,\frac{mi}{h}$ , $\theta_{A} = 180^{\circ}$ , $v_{W} = 10\,\frac{m}{s}$ and $\theta_{W} = 53^{\circ}$ , then the resulting vector is:
