  First of all, act like the < is a =. this helps for the first part. so the equasion would look like 9(2r-5)-3=7r-4
  
  Now simplfy it.
  
  9(2r-5)-3<7r-4
  
  18r-45-3=7r-4
  
  18r-48=7r-4
  
  Now get r on one side.
  
  18r-7r-48=7r-7r-4                        r<4 is the answer
  
  11r-48=-4
  
  Get r alone
  
  11r-48+48=-4+48
  
  11r=44    r=4 r<4  Divide and get the answer for r. Now you go back and see if the inequality changes at all (which it doesn't.)
