    Work: Find the solution of equation (92-2x)(60-x)÷6 = 885 .
    Question type: Equation
    Solution:Original question:
     (922 x )(60 x ) ÷ 6 = 885
    Remove the bracket on the left of the equation:
     Left side of the equation = 92(60 x ) ×

x x = 885

    After the equation is converted into a general formula, it is converted into:
    ( x - 1 )( x - 105 )=0
    From
        x - 1 = 0
        x - 105 = 0

    it is concluded that::
        x1=1
        x2=105
    
    There are 2 solution(s).
