[ 1/1 Equation]
    Work: Find the solution of equation 2/(x+2)+3/(x-2) = 4 .
    Question type: Equation
    Solution:Original question:
     2 ÷ ( x + 2) + 3 ÷ ( x 2) = 4
     Multiply both sides of the equation by:( x + 2)
     2 + 3 ÷ ( x 2) × ( x + 2) = 4( x + 2)
    Remove a bracket on the left of the equation::
     2 + 3 ÷ ( x 2) × x + 3 ÷ ( x 2) × 2 = 4( x + 2)
    Remove a bracket on the right of the equation::
     2 + 3 ÷ ( x 2) × x + 3 ÷ ( x 2) × 2 = 4 x + 4 × 2
    The equation is reduced to :
     2 + 3 ÷ ( x 2) × x + 6 ÷ ( x 2) = 4 x + 8
     Multiply both sides of the equation by:( x 2)
     2( x 2) + 3 x + 6 = 4 x ( x 2) + 8( x 2)
    Remove a bracket on the left of the equation:
     2 x 2 × 2 + 3 x + 6 = 4 x ( x 2) + 8( x 2)
    Remove a bracket on the right of the equation::
     2 x 2 × 2 + 3 x + 6 = 4 x x 4 x × 2 + 8( x 2)
    The equation is reduced to :
     2 x 4 + 3 x + 6 = 4 x x 8 x + 8( x 2)
    The equation is reduced to :
     5 x + 2 = 4 x x 8 x + 8( x 2)
    Remove a bracket on the right of the equation::
     5 x + 2 = 4 x x 8 x + 8 x 8 × 2
    The equation is reduced to :
     5 x + 2 = 4 x x 8 x + 8 x 16
    The equation is reduced to :
     5 x + 2 = 4 x x 0 x 16

    The solution of the equation:
        x1≈-1.586476 , keep 6 decimal places
        x2≈2.836476 , keep 6 decimal places
    
    There are 2 solution(s).
