[ 1/1 Equation]
    Work: Find the solution of equation 2X-8000/2X+8000 = 0 .
    Question type: Equation
    Solution:Original question:
     2 X 8000 ÷ 2 × X + 8000 = 0
     Left side of the equation = 2 X 4000 X + 8000
                                             = - 3998 X + 8000
    The equation is transformed into :
      - 3998 X + 8000 = 0

    Transposition :
      - 3998 X = 08000

    Combine the items on the right of the equation:
      - 3998 X = - 8000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     8000 = 3998 X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     3998 X = 8000

    The coefficient of the unknown number is reduced to 1 :
      X = 8000 ÷ 3998
        = 8000 ×
1
3998
        = 4000 ×
1
1999

    We obtained :
      X =
4000
1999
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 2.001001
