−

728 125

X

=

X

+

247 1000

X

    The equation is reduced to :

54000

−

728 125

X

=

1729 1000

X

    Transposition :

-

728 125

X

−

1729 1000

X

=

-

54000

    Combine the items on the left of the equation:

-

7553 1000

X

=

-

54000

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

54000

=

7553 1000

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 :

7553 1000

X

=

54000

    The coefficient of the unknown number is reduced to 1 :

X

=

54000

÷

7553 1000

=

54000

×

1000 7553

    We obtained :

X

=

54000000 7553

    This is the solution of the equation.

    Convert the result to decimal form :

X

=

7149.477029
