 X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
3
164000
 X =
189
8200

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

    We obtained :
      X = 1260
    This is the solution of the equation.
