 −
2831
9900

    Combine the items on the right of the equation:
     
13
33000
 X =
139
9900

    The coefficient of the unknown number is reduced to 1 :
      X =
139
9900
 ÷

    We obtained :
      X =
1390
39
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 35.641026
