 a − 5166
    The equation is transformed into :
     
207
5
 a − 5166 = 10000

    Transposition :
     
207
5
 a = 10000 + 5166

    Combine the items on the right of the equation:
     
207
5
 a = 15166

    The coefficient of the unknown number is reduced to 1 :
      a = 15166 ÷
207
5
        = 15166 ×
5
207

    We obtained :
      a =
75830
207
    This is the solution of the equation.

    Convert the result to decimal form :
      a = 366.328502
