Detail solution
Given the equation:
$$\left(- \frac{6}{x} + \frac{10}{x}\right) + 8 = 0$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 1

b1 = 1/8

a2 = 1

b2 = -x/4

so we get the equation
$$- \frac{x}{4} = \frac{1}{8}$$
$$- \frac{x}{4} = \frac{1}{8}$$
Divide both parts of the equation by -1/4
x = 1/8 / (-1/4)

We get the answer: x = -1/2
