[ 1/1 Equation]
    Work: Find the solution of equation (e(0.294432*x-12.955)/(1+(e(0.294432*x-12.955)) ) ) = 0 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( x + 2500 )( x + 2500 )
    From
        x + 2500 = 0
        x + 2500 = 0

    it is concluded that::
        x1=-2500
        x2=-2500
    Solutions that cannot be obtained by factorization:
        x3≈-2498.535597 , keep 6 decimal places
        x4≈-2497.071193 , keep 6 decimal places
        x5≈-2495.606790 , keep 6 decimal places
        x6≈-2494.142387 , keep 6 decimal places
        x7≈-2492.677984 , keep 6 decimal places
        x8≈-2491.213580 , keep 6 decimal places
        x9≈-2489.749177 , keep 6 decimal places
        x10≈-2488.284774 , keep 6 decimal places
    
    There are 10 solution(s).
