    The equation is transformed into :
     
240381
1000
 +
3
100
 a =
12509
100
 + a

    Transposition :
     
3
100
 a − a =
12509
100
 −
240381
1000

    Combine the items on the left of the equation:
     - 
97
100
 a =
12509
100
 −
240381
1000

    Combine the items on the right of the equation:
     - 
97
100
 a = -
115291
1000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
115291
1000
 =
97
100
 a

    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 :
     
97
100
 a =
115291
1000

    The coefficient of the unknown number is reduced to 1 :
      a =
115291
1000
 ÷
97
100
        =
115291

97

    We obtained :
      a =
115291
970
    This is the solution of the equation.

    Convert the result to decimal form :
      a = 118.856701
