[ 1/1 Equation]
    Work: Find the solution of equation (-m-1)÷(6-3m) = 4 .
    Question type: Equation
    Solution:Original question:

(

-

m

−

1

)

÷

(

6

−

3

m

)

=

4

Multiply both sides of the equation by:

(

6

−

3

m

)

(

-

m

−

1

)

=

4

(

6

−

3

m

)

    Remove a bracket on the left of the equation:：

-

m

−

1

=

4

(

6

−

3

m

)

    Remove a bracket on the right of the equation:：

-

m

−

1

=

4

×

6

−

4

×

3

m

    The equation is reduced to :

-

m

−

1

=

24

−

12

m

    Transposition :

-

m

+

12

m

=

24

+

1

    Combine the items on the left of the equation:

11

m

=

24

+

1

    Combine the items on the right of the equation:

11

m

=

25

    The coefficient of the unknown number is reduced to 1 :

m

=

25

÷

11

=

25

×

1 11

    We obtained :

m

=

25 11

    This is the solution of the equation.

    Convert the result to decimal form :

m

=

2.272727
