[ 1/1 Equation]
    Work: Find the solution of equation 6/(x-3) = (x+2)/6 .
    Question type: Equation
    Solution:Original question:
     6 ÷ ( x 3) = ( x + 2) ÷ 6
     Multiply both sides of the equation by:( x 3)
     6 = ( x + 2) ÷ 6 × ( x 3)
    Remove a bracket on the right of the equation::
     6 = x ÷ 6 × ( x 3) + 2 ÷ 6 × ( x 3)
    The equation is reduced to :
     6 = x ×
1
6
( x 3) +

    Remove a bracket on the right of the equation::
     6 = x ×

    After the equation is converted into a general formula, it is converted into:
    ( x + 6 )( x - 7 )=0
    From
        x + 6 = 0
        x - 7 = 0

    it is concluded that::
        x1=-6
        x2=7
    
    There are 2 solution(s).
