100
     Left side of the equation = 34 X +
9
5
X
                                             =
179
5
X
    The equation is transformed into :
     
179
5
X = 17000 ×
53
100
     Right side of the equation = 9010
    The equation is transformed into :
     
179
5
X = 9010

    The coefficient of the unknown number is reduced to 1 :
      X = 9010 ÷
179
5
        = 9010 ×
