[ 1/1 Equation]
    Work: Find the solution of equation (2x+3)/4+4/(2x+3) = (4-x)/3+3/(4-x) .
    Question type: Equation
    Solution:Original question:
     (2 x + 3) ÷ 4 + 4 ÷ (2 x + 3) = (4 x ) ÷ 3 + 3 ÷ (4 x )
     Multiply both sides of the equation by:(2 x + 3) ,  (4 x )
     (2 x + 3) ÷ 4 × (2 x + 3)(4 x ) + 4(4 x ) = (4 x ) ÷ 3 × (2 x + 3)(4 x ) + 3(2 x + 3)
    Remove a bracket on the left of the equation::
     2 x ÷ 4 × (2 x + 3)(4 x ) + 3 ÷ 4 × (2 x + 3)(4 x ) + 4(4 x ) = (4 x ) ÷ 3 × (2 x + 3)(4 x ) + 3(2 x + 3)
    Remove a bracket on the right of the equation::
     2 x ÷ 4 × (2 x + 3)(4 x ) + 3 ÷ 4 × (2 x + 3)(4 x ) + 4(4 x ) = 4 ÷ 3 × (2 x + 3)(4 x ) x ÷ 3 × (2 x + 3)(4 x ) + 3(2 x + 3)

    After the equation is converted into a general formula, it is converted into:
    ( x - 0 )( 10x - 7 )( 2x - 5 )=0
    From
        x - 0 = 0
        10x - 7 = 0
        2x - 5 = 0

    it is concluded that::
        x1=0
        x2=
