[ 1/1 Equation]
    Work: Find the solution of equation (180-3x)x-(180-3x)20 = 900 .
    Question type: Equation
    Solution:Original question:
     (1803 x ) x (1803 x ) × 20 = 900
    Remove the bracket on the left of the equation:
     Left side of the equation = 180 x 3 x x (1803 x ) × 20
                                             = 180 x 3 x x 180 × 20 + 3 x × 20
                                             = 180 x 3 x x 3600 + 60 x
                                             = 240 x 3 x x 3600
    The equation is transformed into :
     240 x 3 x x 3600 = 900

    After the equation is converted into a general formula, it is converted into:
    ( x - 30 )( x - 50 )=0
    From
        x - 30 = 0
        x - 50 = 0

    it is concluded that::
        x1=30
        x2=50
    
    There are 2 solution(s).
