[ 1/1 Equation]
    Work: Find the solution of equation (415-x)/(415*x*(x-1)) = 0.0015 .
    Question type: Equation
    Solution:Original question:
     (415 x ) ÷ (415 x ( x 1)) =
3
2000
     Multiply both sides of the equation by:(415 x ( x 1))
     (415 x ) =
3
2000
(415 x ( x 1))
    Remove a bracket on the left of the equation::
     415 x =
3
2000
(415 x ( x 1))
    Remove a bracket on the right of the equation::
     415 x =
3
2000
× 415 x ( x 1)
    The equation is reduced to :
     415 x =
249
400
x ( x 1)
    Remove a bracket on the right of the equation::
     415 x =
249
400
x x
249
400
x × 1
    The equation is reduced to :
     415 x =
249
400
x x
249
400
x

    After the equation is converted into a general formula, it is converted into:
    ( 1000x +√682509467 )( √9999x - √6511265 )=0
    From
        1000x +√682509467 = 0
        √9999x - √6511265 = 0

    it is concluded that::
        x1=-
√682509467
1000
        x2=
√6511265
√9999
    
    There are 2 solution(s).
