[ 1/1 Equation]
    Work: Find the solution of equation 2000+[50*x+200]*(10-x)+4x*[600-50*x+200]-600*6 = 1050 .
    Question type: Equation
    Solution:Original question:
     2000 + (50 x + 200)(10 x ) + 4 x (60050 x + 200)600 × 6 = 1050
     Left side of the equation = 2000 + (50 x + 200)(10 x ) + 4 x (60050 x + 200)3600
                                             = - 1600 + (50 x + 200)(10 x ) + 4 x (60050 x + 200)
    The equation is transformed into :
      - 1600 + (50 x + 200)(10 x ) + 4 x (60050 x + 200) = 1050
    Remove the bracket on the left of the equation:
     Left side of the equation = - 1600 + 50 x (10 x ) + 200(10 x ) + 4 x (60050 x + 200)
                                             = - 1600 + 50 x × 1050 x x + 200(10 x ) + 4 x (60050 x + 200)
                                             = - 1600 + 500 x 50 x x + 200(10 x ) + 4 x (60050 x + 200)
                                             = - 1600 + 500 x 50 x x + 200 × 10200 x + 4 x
                                             = - 1600 + 500 x 50 x x + 2000200 x + 4 x (60050 x + 200)
                                             = 400 + 300 x 50 x x + 4 x (60050 x + 200)
                                             = 400 + 300 x 50 x x + 4 x × 6004 x × 50
                                             = 400 + 300 x 50 x x + 2400 x 200 x x + 800
                                             = 400 + 3500 x 50 x x 200 x x
    The equation is transformed into :
     400 + 3500 x 50 x x 200 x x = 1050

    The solution of the equation:
        x1≈0.188245 , keep 6 decimal places
        x2≈13.811755 , keep 6 decimal places
    
    There are 2 solution(s).
