    The equation is transformed into :
     
2097
2500
 x −
699
5
 = 0

    Transposition :
     
2097
2500
 x = 0 +
699
5

    Combine the items on the right of the equation:
     
2097
2500
 x =
699
5

    The coefficient of the unknown number is reduced to 1 :
      x =
699
5
 ÷

699

    We obtained :
      x =
116500
699
    This is the solution of the equation.

    By reducing fraction, we can get:
      x =
500
3

    Convert the result to decimal form :
      x = 166.666667
