    Work: Find the solution of equation (x-3)/2+(x-2)/3 = 2/(x-3)+3/(x-2) .
    Question type: Equation
    Solution:Original question:
     ( x 3) ÷ 2 + ( x 2) ÷ 3 = 2 ÷ ( x 3) + 3 ÷ ( x 2)
     Multiply both sides of the equation by:( x 3)
     ( x 3) ÷ 2 × ( x 3) + ( x 2) ÷ 3 × ( x 3) = 2 + 3 ÷ ( x 2) × ( x 3)
    Remove a bracket on the left of the equation::
      x ÷ 2 × ( x 3)3 ÷ 2 × ( x 3) + ( x 2) ÷ 3 × ( x 3) = 2 + 3 ÷ ( x 2) × ( x 3)
    Remove a bracket on the right of the equation::
      x ÷ 2 × ( x 3)3 ÷ 2 × ( x 3) + ( x 2) ÷ 3 × ( x 3) = 2 + 3 ÷ ( x 2) × x 3 ÷ ( x 2) × 3

x = 5 x 13

    After the equation is converted into a general formula, it is converted into:
    ( x +0 )( 5x - 13 )( x - 5 )=0
    From
        x + 0 = 0
        5x - 13 = 0
        x - 5 = 0

    it is concluded that::
        x1=0
        x2=

        x3=5
    
    There are 3 solution(s).
