    The equation is transformed into :
     
10741322
65
 x = 450000

    The coefficient of the unknown number is reduced to 1 :
      x = 450000 ÷
10741322
65
        = 450000 ×
65
10741322
        = 225000 ×

    We obtained :
      x =
14625000
5370661
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 2.723128
