  What is the full question? What are you supposed to do?

  I assume you want to mean simplify?

  To simplify, you multiply (1-x) to the numerator and the denominator.
  Then you get

  ( 1 - x + 1 + x ) / ( 1 - x - 1 - x)
  2 / (-2x)
  - 1/x (shown)

  required to prove LHS = RHS?

  assume x <> 1, (which would give a division by zero error in the original equation anyway)

  replace the 2 one's on the left (1 in the numerator and 1 in the denomiator) with "(1 - x) / (1 - x)"

  i.e.

  numerator : (1 - x) / (1 - x) + (1 + x) / (1 - x)

  denominator : (1 - x) / (1 - x) - (1 + x) / (1 - x)

  simplify...
