The equation to solve for $x$ is:

$-2 - 6y = 8x$

Let's solve for $x$:

1. Start by isolating $x$ on one side. First, divide both sides by 8:

$x = \frac{-2 - 6y}{8}$

2. Simplify the expression:

$x = \frac{-2}{8} - \frac{6y}{8}$

3. This simplifies to:

$x = -\frac{1}{4} - \frac{3y}{4}$

Thus, the solution for $x$ is:

$x = -\frac{1}{4} - \frac{3y}{4}$
