    Question type: Equation
    Solution:Original question:

(

193718

−

x

)

÷

x

×

100 100

=

0

Multiply both sides of the equation by:

x

(

193718

−

x

)

×

100 100

=

0

    Remove a bracket on the left of the equation:：

193718

×

100 100

−

x

×

100 100

=

0

    The equation is reduced to :

193718

−

x

×

100 100

=

0

    Transposition :

-

100 100

x

=

0

−

193718

    Combine the items on the right of the equation:

-

100 100

x

=

-

193718

193718

=

100 100

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 :

100 100

x

=

193718

=

193718

×

100 100

=

96859

×

100 50

    We obtained :

x

=

9685900 50

    This is the solution of the equation.
