Answer:
The vale of x is 3/5.
Step-by-step explanation:
First you have to expand out :
![2(5x - 3)](https://tex.z-dn.net/?f=2%285x%20-%203%29)
![= 2(5x) - 2(3)](https://tex.z-dn.net/?f=%20%3D%202%285x%29%20-%202%283%29)
![= 10x - 6](https://tex.z-dn.net/?f=%20%3D%2010x%20-%206)
Next you have to solve it by adding 6 to both sides :
Let expression = 0,
![10x - 6 = 0](https://tex.z-dn.net/?f=10x%20-%206%20%3D%200)
![10x - 6 + 6 = 0 + 6](https://tex.z-dn.net/?f=10x%20-%206%20%2B%206%20%3D%200%20%2B%206)
![10x = 6](https://tex.z-dn.net/?f=10x%20%3D%206)
![x = \frac{6}{10}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B6%7D%7B10%7D%20)
![x = \frac{3}{5}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B3%7D%7B5%7D%20)
