[ 1/1 Equation]
    Work: Find the solution of equation 0.1/(1+0.20326x)+0.9/(1-0.9999984x) = 0 .
    Question type: Equation
    Solution:Original question:

÷ (1 +
10163
50000
x ) +
9
10
÷ (1
624999
625000
x ) = 0
     Multiply both sides of the equation by:(1 +
10163
50000
x )
     
1
10
+
9
10
÷ (1
624999
625000
x ) × (1 +
10163
50000
x ) = 0
    Remove a bracket on the left of the equation::

x = 0
    The equation is reduced to :

x ) +
91467
500000
÷ (1

x = 0

    After the equation is converted into a general formula, there is a common factor:
    ( x - 1 )
    From
        x - 1 = 0

    it is concluded that::
        x1=1, it is the incremental root of the eqution.

    Solutions that cannot be obtained by factorization:
        x2≈-12.057758 , keep 6 decimal places
        x3≈-4.919807 , keep 6 decimal places
    
    There are 3 solution(s).

    There is(are) 1 additive root(s) and 2 real solutions.
(Note:additive root, generated by computer, but not suitable for this equation.)
