Pablo ran farther, the work I did is below. I used an LCD (Lowest common denominator) to solve the problem.
Use slope 3x and show that 2 slopes are negative reciprocals of each other
Using the data you gave I made an equation
(x+3+11+9+7+3)/6 = x
(The formula for finding the mean is the sum of observations divided by total no of observations)
And I equated it (refer the picture)
x = 33/5 = 6.6
Hope this helped you!
