    Work: Find the solution of equation (9000-0.466*x)/(49.5*x) = 0.038 .
    Question type: Equation
    Solution:Original question:

(

9000

−

233 500

x

)

÷

(

99 2

x

)

=

19 500

Multiply both sides of the equation by:

(

99 2

x

)

(

9000

−

233 500

x

)

=

19 500

(

99 2

x

)

    Remove a bracket on the left of the equation:：

9000

−

233 500

x

=

19 500

(

99 2

x

)

    Remove a bracket on the right of the equation:：

9000

−

233 500

x

=

19 500

×

99 2

x

    The equation is reduced to :

9000

−

233 500

x

=

1881 1000

x

    Transposition :

-

233 500

x

−

1881 1000

x

=

-

9000

    Combine the items on the left of the equation:

-

2347 1000

x

=

-

9000

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

9000

=

2347 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 :

2347 1000

x

=

9000

    The coefficient of the unknown number is reduced to 1 :

x

=

9000

÷

2347 1000

=

9000

×

1000 2347

    We obtained :

x

=

9000000 2347

    This is the solution of the equation.

    Convert the result to decimal form :

x

=

3834.682573
