    The equation is transformed into :
     
2144443
1000
+
10
100
a =
41111
25
+ a

    Transposition :
     
10
100
a a =
41111
25
2144443
1000

    Combine the items on the left of the equation:
     
9
10
a =
41111
25
2144443
1000

    Combine the items on the right of the equation:
     
9
10
a = -
500003
1000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
500003
1000
=
9
10
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 :
     
9
10
a =
500003
1000

    The coefficient of the unknown number is reduced to 1 :
      a =
500003
1000
÷

    We obtained :
      a =
500003
900
    This is the solution of the equation.

    Convert the result to decimal form :
      a = 555.558889
