Answer:
Option D is correct.
Value of x is in the solution set of given equation is., 4
Step-by-step explanation:
Given that:
.....[1]
Find the value of x is in the solution set;
Add 5x to both sides of equation [1];
Simplify:

Add 3 to both sides we get;

Divide both sides by 7 we get;
x > 2.
Then, we have the solution set for x is: 
Therefore, the value of x is in the solution set is, 4
