[ 1/1 Equation]
    Work: Find the solution of equation 1/(x+31/2)+1/(x+1/2) = 2/x+1/(x-6) .
    Question type: Equation
    Solution:Original question:
     1 ÷ ( x + 31 ÷ 2) + 1 ÷ ( x + 1 ÷ 2) = 2 ÷ x + 1 ÷ ( x 6)
     Multiply both sides of the equation by:( x + 31 ÷ 2) ,   x
     1 x + 1 ÷ ( x + 1 ÷ 2) × ( x + 31 ÷ 2) x = 2( x + 31 ÷ 2) + 1 ÷ ( x 6) × ( x + 31 ÷ 2) x
    Remove a bracket on the left of the equation::
     1 x + 1 ÷ ( x + 1 ÷ 2) × x x + 1 ÷ ( x + 1 ÷ 2) × 31 ÷ 2 × x = 2( x + 31 ÷ 2) + 1 ÷ ( x 6) × ( x + 31 ÷ 2) x
    Remove a bracket on the right of the equation::
     1 x + 1 ÷ ( x + 1 ÷ 2) × x x + 1 ÷ ( x + 1 ÷ 2) × 31 ÷ 2 × x = 2 x + 2 × 31 ÷ 2 + 1 ÷ ( x 6) × ( x + 31 ÷ 2) x
    The equation is reduced to :
     1 x + 1 ÷ ( x + 1 ÷ 2) × x x +
31
2
÷ ( x + 1 ÷ 2) × x = 2 x + 31 + 1 ÷ ( x 6) × ( x + 31 ÷ 2) x
     Multiply both sides of the equation by:( x + 1 ÷ 2) ,  ( x 6)
     1 x ( x + 1 ÷ 2)( x 6) + 1 x x ( x 6) +

x ( x 6) = 2 x ( x + 1 ÷ 2)( x 6) + 31( x + 1 ÷ 2)( x 6) + 1( x + 31 ÷ 2) x ( x + 1 ÷ 2)
    Remove a bracket on the left of the equation:
     1 x x ( x 6) + 1 x × 1 ÷ 2 × ( x 6) + 1 x x = 2 x ( x + 1 ÷ 2)( x 6) + 31( x + 1 ÷ 2)( x 6) + 1( x + 31 ÷ 2) x ( x + 1 ÷ 2)
    Remove a bracket on the right of the equation::
     1 x x ( x 6) + 1 x × 1 ÷ 2 × ( x 6) + 1 x x = 2 x x ( x 6) + 2 x × 1 ÷ 2 × ( x 6) + 31( x + 1 ÷ 2)( x 6)

2
x ( x 6) + 1 = 2 x x ( x 6) + 1 x ( x 6) + 31( x + 1 ÷ 2)( x 6) + 1( x + 31 ÷ 2)
    Remove a bracket on the right of the equation::
     1 x x x 1 x x × 6 +
