    L - S = 18
    L + S = 34
    
    L = 18 + S
    
    (18 + S) + S = 34
    18 + 2S = 34
    2S = 34 - 18
    2S = 18
    S = ?
    L = ?

  First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
  
  See my answer to your later post.
  
  Thanks for asking.
