    Work: Find the solution of equation （x-2.1823）/x = -1.08% .
    Question type: Equation
    Solution:Original question:

(

x

−

21823 10000

)

÷

x

=

-

27 2500

Multiply both sides of the equation by:

x

(

x

−

21823 10000

)

=

-

27 2500

x

    Remove a bracket on the left of the equation:：

x

−

21823 10000

=

-

27 2500

x

    Transposition :

x

+

27 2500

x

=

21823 10000

    Combine the items on the left of the equation:

2527 2500

x

=

21823 10000

    The coefficient of the unknown number is reduced to 1 :

x

=

21823 10000

÷

2527 2500

=

21823 10000

×

2500 2527

=

21823 4

×

1 2527

    We obtained :

x

=

21823 10108

    This is the solution of the equation.
