-8*x-6>0 inequation

Given the inequality:
$$- 8 x - 6 > 0$$
To solve this inequality, we must first solve the corresponding equation:
$$- 8 x - 6 = 0$$
Solve:
Given the linear equation:

-8*x-6 = 0

Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 6$$
Divide both parts of the equation by -8

x = 6 / (-8)

$$x_{1} = - \frac{3}{4}$$
$$x_{1} = - \frac{3}{4}$$
This roots
$$x_{1} = - \frac{3}{4}$$
is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{1}$$
For example, let's take the point
$$x_{0} = x_{1} - \frac{1}{10}$$
=
$$- \frac{3}{4} + - \frac{1}{10}$$
=
$$- \frac{17}{20}$$
substitute to the expression
$$- 8 x - 6 > 0$$
$$-6 - \frac{\left(-17\right) 8}{20} > 0$$

4/5 > 0

the solution of our inequality is:
$$x < - \frac{3}{4}$$
