[ 1/1 Equation]
    Work: Find the solution of equation -x/(1+x*x) = 0.0872/2 .
    Question type: Equation
    Solution:Original question:
      - x ÷ (1 + x x ) =
109
1250
÷ 2
     Multiply both sides of the equation by:(1 + x x )
      - x =
109
1250
÷ 2 × (1 + x x )
    Remove a bracket on the right of the equation::
      - x =
109
1250
÷ 2 × 1 +
109
1250
÷ 2 × x x
    The equation is reduced to :
      - x =
109
2500
+
109
2500
x x

    The solution of the equation:
        x1≈-22.892097 , keep 6 decimal places
        x2≈-0.043683 , keep 6 decimal places
    
    There are 2 solution(s).
