Answer:
Option B:
is the correct answer.
Step-by-step explanation:
Given expression is:

We have to find the value of x.
Multiplying both sides by r

Now, we will subtract t from both sides of the equation
sr - t = 2x+t-t
sr-t = 2x
2x = sr-t
Dividing both sides of equation by 2

Hence,
Option B:
is the correct answer.
