1250
 X + 126
    The equation is transformed into :
     
449
1250
 X + 126 = 560

    Transposition :
     
449
1250
 X = 560 − 126

    Combine the items on the right of the equation:
     
449
1250
 X = 434

    The coefficient of the unknown number is reduced to 1 :
      X = 434 ÷
449
1250
        = 434 ×
1250
449

    We obtained :
      X =
542500
449
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 1208.240535
