Respuesta :

r = 9 is the answer to your question.

I hope this helps you in any way. :)

9(r) - 7 - 74 = ? 
  9(r)  - 81 
     You have to solve this part  → 9 = ___ [ the answer that goes inside of the blank is '0']
              We have to solve this one too! →(r)  - 9 = 0 
             Since, this is the case we have to add ( + ) from the number 9 on each of your sides to make it more simpler

We have one solution in this particular problem..

Therefore, the value of "r" is 9
