20
 X + 27489
    The equation is transformed into :
     
8901
20
 X + 27489 = 600000

    Transposition :
     
8901
20
 X = 600000 − 27489

    Combine the items on the right of the equation:
     
8901
20
 X = 572511

    The coefficient of the unknown number is reduced to 1 :
      X = 572511 ÷
8901
20
        = 572511 ×
20
8901
        = 190837 ×

2967

    We obtained :
      X =
3816740
2967
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 1286.397034
