100
 X + 345885
    The equation is transformed into :
     
20013
100
 X + 345885 = 600000

    Transposition :
     
20013
100
 X = 600000 − 345885

    Combine the items on the right of the equation:
     
20013
100
 X = 254115

    The coefficient of the unknown number is reduced to 1 :
      X = 254115 ÷
20013
100
        = 254115 ×
100
20013
        = 84705 ×
100
6671

    We obtained :
      X =
8470500
6671
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 1269.749663
