    Work: Find the solution of equation （0.6x+6）➗（0.4x+14） = 1.2 .
    Question type: Equation
    Solution:Original question:

(

3 5

x

+

6

)

÷

(

2 5

x

+

14

)

=

6 5

Multiply both sides of the equation by:

(

2 5

x

+

14

)

(

3 5

x

+

6

)

=

6 5

(

2 5

x

+

14

)

    Remove a bracket on the left of the equation:：

3 5

x

+

6

=

6 5

(

2 5

x

+

14

)

    Remove a bracket on the right of the equation:：

3 5

x

+

6

=

6 5

×

2 5

x

+

6 5

×

14

    The equation is reduced to :

3 5

x

+

6

=

12 25

x

+

84 5

    Transposition :

3 5

x

−

12 25

x

=

84 5

−

6

    Combine the items on the left of the equation:

3 25

x

=

84 5

−

6

    Combine the items on the right of the equation:

3 25

x

=

54 5

    The coefficient of the unknown number is reduced to 1 :

x

=

54 5

÷

3 25

=

54 5

×

25 3

=

18

×

5

    We obtained :

x

=

90

    This is the solution of the equation.
