    The equation is transformed into :
     
309
250
 x = 420000

    The coefficient of the unknown number is reduced to 1 :
      x = 420000 ÷
309
250
        = 420000 ×
250
309
        = 140000 ×

    We obtained :
      x =
35000000
103
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 339805.825243
