[ 1/1 Equation]
    Work: Find the solution of equation （80-2x）（1200+200*80-2x/x）-1600X-64000 = 122000 .
    Question type: Equation
    Solution:Original question:
     (80 − 2 x )(1200 + 200 × 80 − 2 x ÷ x ) − 1600 x − 64000 = 122000
    Remove a bracket on the left of the equation:：
     80(1200 + 200 × 80 − 2 x ÷ x ) − 2 x (1200 + 200 × 80 − 2 x ÷ x ) − 1600 x − 64000 = 122000
    Remove a bracket on the left of the equation:
     80 × 1200 + 80 × 200 × 80 − 80 × 2 x ÷ x − 2 x (1200 + 200 × 80 − 2 x ÷ x ) = 122000
    The equation is reduced to :
     96000 + 1280000 − 160 x ÷ x − 2 x (1200 + 200 × 80 − 2 x ÷ x ) − 1600 x − 64000 = 122000
    The equation is reduced to :
     1312000 − 160 x ÷ x − 2 x (1200 + 200 × 80 − 2 x ÷ x ) − 1600 x = 122000
    Remove a bracket on the left of the equation:
     1312000 − 160 × 1 ÷ 1 − 2 x × 1200 − 2 x × 200 × 80 + 2 = 122000
    The equation is reduced to :
     1312000 − 160 − 2400 x − 32000 x + 4 x x ÷ x − 1600 x = 122000
    The equation is reduced to :
     1311840 − 36000 x + 4 x x ÷ x = 122000

    Transposition :
      - 36000 x + 4 × 1 x ÷ 1 = 122000 − 1311840

    Calculate the items on the left of the equation:
      - 36000 x + 4 x = 122000 − 1311840

    Combine the items on the left of the equation:
      - 35996 x = 122000 − 1311840

    Combine the items on the right of the equation:
      - 35996 x = - 1189840

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     1189840 = 35996 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 :
     35996 x = 1189840

    The coefficient of the unknown number is reduced to 1 :
      x = 1189840 ÷ 35996
        = 1189840 ×
1
35996
        = 297460 ×
1
8999

    We obtained :
      x =
297460
8999
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 33.054784
