[ 1/1 Equation]
    Work: Find the solution of equation (12-3x)(16-9x) = 32 .
    Question type: Equation
    Solution:Original question:
     (123 x )(169 x ) = 32
    Remove the bracket on the left of the equation:
     Left side of the equation = 12(169 x )3 x (169 x )
                                             = 12 × 1612 × 9 x 3 x (169 x )
                                             = 192108 x 3 x (169 x )
                                             = 192108 x 3 x × 16 + 3 x × 9 x
                                             = 192108 x 48 x + 27 x x
                                             = 192156 x + 27 x x
    The equation is transformed into :
     192156 x + 27 x x = 32

    After the equation is converted into a general formula, it is converted into:
    ( 3x - 4 )( 9x - 40 )=0
    From
        3x - 4 = 0
        9x - 40 = 0

    it is concluded that::
        x1=
4
3
        x2=
40
9
    
    There are 2 solution(s).
