[ 1/1 Equation]
    Work: Find the solution of equation (x/(2-x))/(1-x)/(1-x)*(2-x)*(2-x) = 0.99 .
    Question type: Equation
    Solution:Original question:
     ( x ÷ (2 x )) ÷ (1 x ) ÷ (1 x ) × (2 x )(2 x ) =
99
100
     Multiply both sides of the equation by:(1 x )
     ( x ÷ (2 x )) ÷ (1 x ) × (2 x )(2 x ) =
