[ 1/1 Equation]
    Work: Find the solution of equation （9%-x）/(9%-6%) = 0 .
    Question type: Equation
    Solution:Original question:

(

9 100

−

x

)

÷

(

9 100

−

6 100

)

=

0

Multiply both sides of the equation by:

(

9 100

−

6 100

)

(

9 100

−

x

)

=

0

    Remove a bracket on the left of the equation:：

9 100

−

x

=

0

    Transposition :

-

x

=

0

−

9 100

    Combine the items on the right of the equation:

-

x

=

-

9 100

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

9 100

=

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 :

x

=

9 100

    This is the solution of the equation.
    This is the solution of the equation.
