Answer:
Option B that is x=4 is correct
Step-by-step explanation:
We have been given an equation 5(x-10) = 30 -15x
we will solve left hand side by opening the parenthesis we will get 5x -50 on left hand side of the equation finally our equation will become
5x - 50 =30 -15x
Taking terms with variables at one side and constant on the other side we will get
5x+15x = 30+50
After solving above equation we will get
20x=80
Hence, x=4
Therefore, Option 2 is correct
