    The equation is transformed into :
     
10000
9151
y
3998987
45755
=

3999
y 100

    Transposition :
     
10000
9151
y
5000
3999
y = - 100 +
3998987
45755

    Combine the items on the left of the equation:
      -
5765000
36594849
y = - 100 +
3998987
45755

    Combine the items on the right of the equation:
      -
5765000
36594849
y = -
576513
45755

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
576513
45755
=
5765000
36594849
y

    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 :
     
5765000
36594849
y =
576513
45755

    The coefficient of the unknown number is reduced to 1 :
      y =
576513
45755
÷
5765000
36594849
        =
576513
45755
×
36594849
5765000

    We obtained :
      y =
21097406181537
263777575000
    This is the solution of the equation.
