Answer:
NO!
Step-by-step explanation:
They are not equivalent. We can check this. If you rewrite them as fractions 13/14 and 1/2, you can cross multiply and see if they are equal. Which they are not. Also, you could just guess.... think of 13:14 as 13 out of 14. And 1:2 as 1 out of 2. You can tell that 13/14 is much greater than 1/2.
You have:
2r

6r-21
then move the 6r over to the left and you end up wtih
-4r

-21
Then you divide by -4 and when you do you must flip the inequality so your answer would be
r

21/4
This problem is far beyond my capability this problem is declared to be one of the toughest in the world due to it not agreeing with the quadratic formula
