[ 1/1 Equation]
    Work: Find the solution of equation ((100+x)(1000-2x))/(100*1000) = 0.152 .
    Question type: Equation
    Solution:Original question:
     ((100 + x )(1000 − 2 x )) ÷ (100 × 1000) =
19
125
     Multiply both sides of the equation by:(100 × 1000)
     ((100 + x )(1000 − 2 x )) =
19
125
(100 × 1000)
    Remove a bracket on the left of the equation:：
     (100 + x )(1000 − 2 x ) =
19
125
(100 × 1000)
    Remove a bracket on the right of the equation:：
     (100 + x )(1000 − 2 x ) =
19
125
 × 100 × 1000
    The equation is reduced to :
     (100 + x )(1000 − 2 x ) = 15200
    Remove a bracket on the left of the equation:
     100(1000 − 2 x ) + x (1000 − 2 x ) = 15200
    Remove a bracket on the left of the equation:
     100 × 1000 − 100 × 2 x + x (1000 − 2 x ) = 15200
    The equation is reduced to :
     100000 − 200 x + x (1000 − 2 x ) = 15200
    Remove a bracket on the left of the equation:
     100000 − 200 x + x × 1000 − x × 2 x = 15200
    The equation is reduced to :
     100000 + 800 x − x × 2 x = 15200

    
        x≈-87.054002 , keep 6 decimal places    
    There are 1 solution(s).
