    Work: Find the solution of equation 200+（x+2） = 150x×2 .
    Question type: Equation
    Solution:Original question:

200

+

(

x

+

2

)

=

150

x

×

2

    Remove the bracket on the left of the equation:

Left side of the equation =

200

+

x

+

2

=

202

+

x

    The equation is transformed into :

202

+

x

=

150

x

×

2

Right side of the equation =

300

x

    The equation is transformed into :

202

+

x

=

300

x

    Transposition :

x

−

300

x

=

-

202

    Combine the items on the left of the equation:

-

299

x

=

-

202

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

202

=

299

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 :

299

x

=

202

    The coefficient of the unknown number is reduced to 1 :

x

=

202

÷

299

=

202

×

1 299

    We obtained :

x

=

202 299

    This is the solution of the equation.

    Convert the result to decimal form :

x

=

0.675585
