    The equation is transformed into :
      -
2921
56000
 x = 4500

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      - 4500 =
2921
56000
 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 :
     
2921
56000
 x = - 4500

    The coefficient of the unknown number is reduced to 1 :
      x = - 4500 ÷
2921
56000
        = - 4500 ×
56000
2921

    We obtained :
      x = -
252000000
2921
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 86271.824718
