 −
99031
339900

    Combine the items on the right of the equation:
     
13
33000
 X =
2939
339900

    The coefficient of the unknown number is reduced to 1 :
      X =
2939
339900
 ÷
13
33000
        =
2939

    We obtained :
      X =
323290
14729
    This is the solution of the equation.

    By reducing fraction, we can get:
      X =
29390
1339

    Convert the result to decimal form :
      X = 21.949216
