Answer:
One Solution
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
Step-by-step explanation:
Given
![-10x = -80](https://tex.z-dn.net/?f=-10x%20%3D%20-80)
Required
Determine the number of solution and the value of x
The equation is a linear equation and they have just one solution
Solving further [Divide both sides by -10]
![\frac{-10x}{-10} = \frac{-80}{-10}](https://tex.z-dn.net/?f=%5Cfrac%7B-10x%7D%7B-10%7D%20%3D%20%5Cfrac%7B-80%7D%7B-10%7D)
![x = \frac{-80}{-10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-80%7D%7B-10%7D)
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
Hence;
<em>x has only one value</em>
