    The equation is transformed into :
      -
442629
500
x +
1
125
= 0

    Transposition :
      -
442629
500
x = 0

125

    Combine the items on the right of the equation:
      -
442629
500
x = -
1
125

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
1
125
=
442629
500
x

    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 :
     
442629
500
x =
1
125

    The coefficient of the unknown number is reduced to 1 :
      x =

442629

    We obtained :
      x =
4
442629
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.000009
