Answer:
![x = \frac{-9}{8} , \frac{-10}{7} , \frac{10}{7}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-9%7D%7B8%7D%20%2C%20%5Cfrac%7B-10%7D%7B7%7D%20%2C%20%5Cfrac%7B10%7D%7B7%7D)
Step-by-step explanation:
8x+9=0
8x=-9
![x = \frac{-9}{8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-9%7D%7B8%7D)
or
![49x^{2}-100 = 0](https://tex.z-dn.net/?f=49x%5E%7B2%7D-100%20%3D%200)
,
![(7x+10)(7x-10)=0](https://tex.z-dn.net/?f=%287x%2B10%29%287x-10%29%3D0)
![7x+10=0, 7x-10=0](https://tex.z-dn.net/?f=7x%2B10%3D0%2C%207x-10%3D0)
![7x=-10, 7x=10](https://tex.z-dn.net/?f=7x%3D-10%2C%207x%3D10)
, ![x = \frac{10}{7}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B10%7D%7B7%7D)
2 ? That seems the most logical answer
