    The equation is transformed into :
     
5193262
625
 +
667
625
 x = 9400

    Transposition :
     
667
625
 x = 9400 −
5193262
625

    Combine the items on the right of the equation:
     
667
625
 x =
681738
625

    The coefficient of the unknown number is reduced to 1 :
      x =
681738
625
 ÷
667
625
        =
681738
625

625
667
        = 681738 ×
1
667

    We obtained :
      x =
681738
667
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1022.095952
