    The equation is transformed into :
     
97219600
109
 +
84
2575
 x = x

    Transposition :
     
84
2575
 x − x = -
97219600
109

    Combine the items on the left of the equation:
     - 
2491
2575
 x = -
97219600
109

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
97219600
109
 =
2491
2575
 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 :
     
2491
2575
 x =
97219600
109

    The coefficient of the unknown number is reduced to 1 :
      x =
97219600
109
 ÷
2491
2575
        =

    We obtained :
      x =
