    Work: Find the solution of equation ｛450-20000/（x+20.8）｝*（x+10.4） = 40000 .
    Question type: Equation
    Solution:Original question:
     (450 − 20000 ÷ ( x +
104
5
))( x +

) = 40000
    Remove a bracket on the left of the equation:：
     450( x +
52
5
) − 20000 ÷ ( x +
104
5
) × ( x +
52
5
) = 40000
     Multiply both sides of the equation by:( x +

    Remove a bracket on the left of the equation:
     450 x x + 450 x ×
104
5
 + 4680( x +
104
5
) − 20000( x +
52
5
) = 40000 x + 832000
    The equation is reduced to :
     450 x x + 9360 x + 4680( x +
104
5
) − 20000( x +
52
5
) = 40000 x + 832000
    Remove a bracket on the left of the equation:
     450 x x + 9360 x + 4680 x + 4680 ×
104
5
 − 20000( x +
52
5
) = 40000 x + 832000
    The equation is reduced to :
     450 x x + 9360 x + 4680 x + 97344 − 20000( x +
52
5
) = 40000 x + 832000
    The equation is reduced to :
     450 x x + 14040 x + 97344 − 20000( x +
52
5
) = 40000 x + 832000
    Remove a bracket on the left of the equation:
     450 x x + 14040 x + 97344 − 20000 x − 20000 ×
52
5
 = 40000 x + 832000
    The equation is reduced to :
     450 x x + 14040 x + 97344 − 20000 x − 208000 = 40000 x + 832000
    The equation is reduced to :
     450 x x − 5960 x − 110656 = 40000 x + 832000

    The solution of the equation:
        x1≈-17.508807 , keep 6 decimal places
        x2≈119.642140 , keep 6 decimal places    
    There are 2 solution(s).
