    Combine the items on the left of the equation:
      -
24449563
99070630
 x = -
1278329
9907063
 −

    Combine the items on the right of the equation:
      -
24449563
99070630
 x = -
181203361
99070630

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
181203361
99070630
 =
24449563
99070630
 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 :
     
24449563
99070630
 x =
181203361
99070630

    The coefficient of the unknown number is reduced to 1 :
      x =
181203361
99070630
 ÷
24449563
99070630
        =
