    Work: Find the solution of equation (x+1500)*21% = x .
    Question type: Equation
    Solution:Original question:

(

x

+

1500

)

×

21 100

=

x

    Remove the bracket on the left of the equation:

Left side of the equation =

x

×

21 100

+

1500

×

21 100

=

x

×

21 100

+

315

    The equation is transformed into :

21 100

x

+

315

=

x

    Transposition :

21 100

x

−

x

=

-

315

    Combine the items on the left of the equation:

-

79 100

x

=

-

315

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

315

=

79 100

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 :

79 100

x

=

315

    The coefficient of the unknown number is reduced to 1 :

x

=

315

÷

79 100

=

315

×

100 79

    We obtained :

x

=

31500 79

    This is the solution of the equation.

    Convert the result to decimal form :

x

=

398.734177
