[ 1/1 Equation]
    Work: Find the solution of equation （1800－180）*135*(x－67.5)+180*x*x/2 = 6.6667*9161*(1536－x) .
    Question type: Equation
    Solution:Original question:
     (1800 − 180) × 135( x −
135
2
) + 180 x x ÷ 2 =
66667
10000
 × 9161(1536 − x )
     Left side of the equation = (1800 − 180) × 135( x −
135
2
) + 90 x x
    The equation is transformed into :
     (1800 − 180) × 135( x −
135
2
) + 90 x x =
66667
10000
 × 9161(1536 − x )
    Remove the bracket on the left of the equation:
     Left side of the equation = 1800 × 135( x −
135
2
) − 180 × 135( x −
135
2
) + 90 x x
                                             = 243000( x −
135
2
) − 24300( x −
135
2
) + 90 x x
                                             = 243000 x − 243000 ×
135
2
 − 24300( x −
135
2
) + 90 x x
                                             = 243000 x − 16402500 − 24300( x −
135
2
) + 90 x x
                                             = 243000 x − 16402500 − 24300 x + 24300 ×
135
2
 + 90 x x
                                             = 243000 x − 16402500 − 24300 x + 1640250 + 90 x x
                                             = 218700 x − 14762250 + 90 x x
    The equation is transformed into :
     218700 x − 14762250 + 90 x x =
66667
10000
 × 9161(1536 − x )
     Right side of the equation =
610736387
10000
(1536 − x )
    The equation is transformed into :
     218700 x − 14762250 + 90 x x =
610736387
10000
(1536 − x )
    Remove the bracket on the right of the equation:
     Right side of the equation =
610736387
10000
 × 1536 −
610736387
10000
 x

    the solutions is:
        x≈348.907378 , keep 6 decimal places    
    There are 1 solution(s).
