    Work: Find the solution of equation x/5200-x/4000 = -0.5+0.246 .
    Question type: Equation
    Solution:Original question:

x

÷

5200

−

x

÷

4000

=

-

1 2

+

123 500

Left side of the equation =

-

3 52000

x

    The equation is transformed into :

-

3 52000

x

=

-

1 2

+

123 500

Right side of the equation =

-

127 500

    The equation is transformed into :

-

3 52000

x

=

-

127 500
