[ 1/1 Equation]
    Work: Find the solution of equation (230+x)*(231*50.6+20x) = (231+x)*(230*49.3+23x) .
    Question type: Equation
    Solution:Original question:
     (230 + x )(231 ×
253
5
+ 20 x ) = (231 + x )(230 ×
493
10
+ 23 x )
    Remove the bracket on the left of the equation:
     Left side of the equation = 230(231 ×
253
5
+ 20 x ) + x (231 ×
253
5
+ 20 x )
                                             = 230 × 231 ×
253
5
+ 230 × 20 x + x (231 ×
253
5
+ 20 x )
                                             = 2688378 + 4600 x + x (231 ×
253
5
+ 20 x )
                                             = 2688378 + 4600 x + x × 231 ×
253
5
+ x × 20 x
                                             = 2688378 + 4600 x + x ×
58443
5
+ x × 20 x
                                             = 2688378 +
81443
5
x + x × 20 x
    The equation is transformed into :
     2688378 +
81443
5
x + x × 20 x = (231 + x )(230 ×
493
10
+ 23 x )
    Remove the bracket on the right of the equation:
     Right side of the equation = 231(230 ×
493
10
+ 23 x ) + x (230 ×
493
10
+ 23 x )
                                               = 231 × 230 ×
493
10
+ 231 × 23 x + x (230 ×
493
10
+ 23 x )
                                               = 2619309 + 5313 x + x (230 ×
493
10
+ 23 x )
                                               = 2619309 + 5313 x + x × 230 ×
493
10
+ x × 23 x
                                               = 2619309 + 5313 x + x × 11339 + x × 23 x
                                               = 2619309 + 16652 x + x × 23 x
    The equation is transformed into :
     2688378 +
81443
5
x + x × 20 x = 2619309 + 16652 x + x × 23 x

    The solution of the equation:
        x1≈102.808121 , keep 6 decimal places
        x2≈102.808121 , keep 6 decimal places
    
    There are 2 solution(s).
