[ 1/1 Equation]
    Work: Find the solution of equation 2/(3+1)-3/(x-4) = 8/(3-x) .
    Question type: Equation
    Solution:Original question:
     2 ÷ (3 + 1)3 ÷ ( x 4) = 8 ÷ (3 x )
     Multiply both sides of the equation by:(3 + 1) ,  (3 x )
     2(3 x )3 ÷ ( x 4) × (3 + 1)(3 x ) = 8(3 + 1)
    Remove a bracket on the left of the equation::
     2 × 32 x 3 ÷ ( x 4) × (3 + 1)(3 x ) = 8(3 + 1)
    Remove a bracket on the right of the equation::
     2 × 32 x 3 ÷ ( x 4) × (3 + 1)(3 x ) = 8 × 3 + 8 × 1
    The equation is reduced to :
     62 x 3 ÷ ( x 4) × (3 + 1)(3 x ) = 24 + 8
    The equation is reduced to :
     62 x 3 ÷ ( x 4) × (3 + 1)(3 x ) = 32
     Multiply both sides of the equation by:( x 4)
     6( x 4)2 x ( x 4)3(3 + 1)(3 x ) = 32( x 4)
    Remove a bracket on the left of the equation:
     6 x 6 × 42 x ( x 4)3(3 + 1)(3 x ) = 32( x 4)
    Remove a bracket on the right of the equation::
     6 x 6 × 42 x ( x 4)3(3 + 1)(3 x ) = 32 x 32 × 4
    The equation is reduced to :
     6 x 242 x ( x 4)3(3 + 1)(3 x ) = 32 x 128
    Remove a bracket on the left of the equation:
     6 x 242 x x + 2 x × 43(3 + 1)(3 x ) = 32 x 128
    The equation is reduced to :
     6 x 242 x x + 8 x 3(3 + 1)(3 x ) = 32 x 128
    The equation is reduced to :
     14 x 242 x x 3(3 + 1)(3 x ) = 32 x 128
    Remove a bracket on the left of the equation:
     14 x 242 x x 3 × 3(3 x )3 × 1(3 x ) = 32 x 128
    The equation is reduced to :
     14 x 242 x x 9(3 x )3(3 x ) = 32 x 128
    Remove a bracket on the left of the equation:
     14 x 242 x x 9 × 3 + 9 x 3(3 x ) = 32 x 128
    The equation is reduced to :
     14 x 242 x x 27 + 9 x 3(3 x ) = 32 x 128
    The equation is reduced to :
     23 x 512 x x 3(3 x ) = 32 x 128
    Remove a bracket on the left of the equation:
     23 x 512 x x 3 × 3 + 3 x = 32 x 128
    The equation is reduced to :
     23 x 512 x x 9 + 3 x = 32 x 128
    The equation is reduced to :
     26 x 602 x x = 32 x 128

    The solution of the equation:
        x1≈-7.520797 , keep 6 decimal places
        x2≈4.520797 , keep 6 decimal places
    
    There are 2 solution(s).
