    The equation is transformed into :
     
12241199
8242405980
 X −
4081073
1373734330
 = 3

    Transposition :
     
12241199
8242405980
 X = 3 +
4081073
1373734330

    Combine the items on the right of the equation:
     
12241199
8242405980
 X =
4125284063
1373734330

    The coefficient of the unknown number is reduced to 1 :
      X =
4125284063
1373734330
 ÷

4699559
    This is the solution of the equation.

    By reducing fraction, we can get:
      X =
14119626
6983

    Convert the result to decimal form :
      X = 2022
