[ 1/1 Equation]
    Work: Find the solution of equation x/(x-1) = 3/(2x-2)-2 .
    Question type: Equation
    Solution:Original question:
      x ÷ ( x 1) = 3 ÷ (2 x 2)2
     Multiply both sides of the equation by:( x 1) ,  (2 x 2)
      x (2 x 2) = 3( x 1)2( x 1)(2 x 2)
    Remove a bracket on the left of the equation::
      x × 2 x x × 2 = 3( x 1)2( x 1)(2 x 2)
    Remove a bracket on the right of the equation::
      x × 2 x x × 2 = 3 x 3 × 12( x 1)(2 x 2)
    The equation is reduced to :
      x × 2 x x × 2 = 3 x 32( x 1)(2 x 2)
    Remove a bracket on the right of the equation::
      x × 2 x 2 x = 3 x 32 x (2 x 2) + 2 × 1(2 x 2)
    The equation is reduced to :
      x × 2 x 2 x = 3 x 32 x (2 x 2) + 2(2 x 2)
    Remove a bracket on the right of the equation::
      x × 2 x 2 x = 3 x 32 x × 2 x + 2 x × 2 + 2(2 x 2)
    The equation is reduced to :
      x × 2 x 2 x = 3 x 34 x x + 4 x + 2(2 x 2)
    The equation is reduced to :
      x × 2 x 2 x = 7 x 34 x x + 2(2 x 2)
    Remove a bracket on the right of the equation::
      x × 2 x 2 x = 7 x 34 x x + 2 × 2 x 2 × 2
    The equation is reduced to :
      x × 2 x 2 x = 7 x 34 x x + 4 x 4
    The equation is reduced to :
      x × 2 x 2 x = 11 x 74 x x

    the solutions is:
        x1=
7
6
    
    There are 1 solution(s).
