    The equation is transformed into :
     
1442721
2000
 +
3
100
 a =
63137
100
 + a

    Transposition :
     
3
100
 a − a =
63137
100
 −
1442721
2000

    Combine the items on the left of the equation:
     - 
97
100
 a =
63137
100
 −
1442721
2000

    Combine the items on the right of the equation:
     - 
97
100
 a = -
179981
2000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
179981
2000
 =
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 =
179981
2000

    The coefficient of the unknown number is reduced to 1 :
      a =
179981
2000
 ÷
97
100
        =
179981

97

    We obtained :
      a =
179981
1940
    This is the solution of the equation.

    Convert the result to decimal form :
      a = 92.773711
