x + 225
    The equation is transformed into :
      -
2921
42000
x + 225 = 4500

    Transposition :
      -
2921
42000
x = 4500225

    Combine the items on the right of the equation:
      -
2921
42000
x = 4275

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      - 4275 =
2921
42000
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
42000
x = - 4275

    The coefficient of the unknown number is reduced to 1 :
      x = - 4275 ÷
2921
42000
        = - 4275 ×
42000
2921

    We obtained :
      x = -
179550000
2921
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 61468.675111
