                                               = 9000 X − 2000 − 850000 + 340000
                                               = 9000 X − 512000
    The equation is transformed into :
     
1269383347
2000
 = 9000 X − 512000

    Transposition :
      - 9000 X = - 512000 −
1269383347
2000

    Combine the items on the right of the equation:
      - 9000 X = -
2293383347
2000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
2293383347
2000
 = 9000 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 :
     9000 X =
2293383347
2000

    The coefficient of the unknown number is reduced to 1 :
      X =
2293383347
2000
 ÷ 9000
        =
2293383347
2000
 ×
1
9000

    We obtained :
      X =
2293383347
18000000
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 127.410186
