[ 1/1 Equation]
    Work: Find the solution of equation 2 = 1/(1/(1-x)) .
    Question type: Equation
    Solution:Original question:
     2 = 1 ÷ (1 ÷ (1 x ))
     Multiply both sides of the equation by:(1 ÷ (1 x ))
     2(1 ÷ (1 x )) = 1
    Remove a bracket on the left of the equation::
     2 × 1 ÷ (1 x ) = 1
    The equation is reduced to :
     2 ÷ (1 x ) = 1
     Multiply both sides of the equation by:(1 x )
     2 = 1(1 x )
    Remove a bracket on the right of the equation::
     2 = 1 × 11 x
    The equation is reduced to :
     2 = 11 x

    Transposition :
     1 x = 12
    i.e.
      x = 12

    Combine the items on the right of the equation:
      x = - 1
    However,when simplifying the equation, multiply both sides by (1 ÷ (1 x )), and when
      x = - 1
    , its value is 0. Therefore, the value of this unknown number is not the solution of the equation, and the input to the equation is incorrect.
