[ 1/1 Equation]
    Work: Find the solution of equation (y-20)(-10y+530) = 2340 .
    Question type: Equation
    Solution:Original question:
     ( y 20)( - 10 y + 530) = 2340
    Remove the bracket on the left of the equation:
     Left side of the equation = y ( - 10 y + 530)20( - 10 y + 530)
                                             = - y × 10 y + y × 53020( - 10 y + 530)
                                             = - y × 10 y + 530 y + 20 × 10 y 20 × 530
                                             = - y × 10 y + 530 y + 200 y 10600
                                             = - y × 10 y + 730 y 10600
    The equation is transformed into :
      - y × 10 y + 730 y 10600 = 2340

    The solution of the equation:
        y1≈30.315342 , keep 6 decimal places
        y2≈42.684658 , keep 6 decimal places
    
    There are 2 solution(s).
