Answer:

[tex]x = - \frac{4}{5} \\ [/tex]

Step-by-step explanation:

In order to solve this question we use ratio and proportion

From the question

y = 20 when x = 8

So we have

If y is 20 when x is 8

Then when y is - 2 x is

[tex] \frac{ - 2 \times 8}{20} = - \frac{16}{20} = - \frac{4}{5} \\ [/tex]

We have the final answer as

[tex]x = - \frac{4}{5} \\ [/tex]

Hope this helps you
