[ 1/1 Equation]
    Work: Find the solution of equation 1/(x+1) = 1/x+1/(x+0.5) .
    Question type: Equation
    Solution:Original question:
     1 ÷ ( x + 1) = 1 ÷ x + 1 ÷ ( x +
1

2
) × ( x + 1) x
    Remove a bracket on the right of the equation::
     1 x = 1 x + 1 × 1 + 1 ÷ ( x +
1
2
) × ( x + 1) x
    The equation is reduced to :
     1 x = 1 x + 1 + 1 ÷ ( x +
1
2
) × ( x + 1) x
     Multiply both sides of the equation by:( x +
