[ 1/1 Equation]
    Work: Find the solution of equation 2x(3x-5)-(2x-3)(3x+4) = 3(x+4) .
    Question type: Equation
    Solution:Original question:
     2 x (3 x 5)(2 x 3)(3 x + 4) = 3( x + 4)
    Remove the bracket on the left of the equation:
     Left side of the equation = 2 x × 3 x 2 x × 5(2 x 3)(3 x + 4)
                                             = 6 x x 10 x (2 x 3)(3 x + 4)
                                             = 6 x x 10 x 2 x (3 x + 4) + 3(3 x + 4)
                                             = 6 x x 10 x 2 x × 3 x 2 x × 4
                                             = 6 x x 10 x 6 x x 8 x + 3(3 x + 4)
                                             = 6 x x 18 x 6 x x + 3(3 x + 4)
                                             = 6 x x 18 x 6 x x + 3 × 3 x + 3
                                             = 6 x x 18 x 6 x x + 9 x + 12
                                             = 6 x x 9 x 6 x x + 12
    The equation is transformed into :
     6 x x 9 x 6 x x + 12 = 3( x + 4)
    Remove the bracket on the right of the equation:
     Right side of the equation = 3 x + 3 × 4
                                               = 3 x + 12
    The equation is transformed into :
     6 x x 9 x 6 x x + 12 = 3 x + 12

    the solutions is:
        x=0
    
    There are 1 solution(s).
