[ 1/1 Equation]
    Work: Find the solution of equation 1/x+2/(1+x)+1/(x+0.5) = 0 .
    Question type: Equation
    Solution:Original question:
     1 ÷ x + 2 ÷ (1 + x ) + 1 ÷ ( x +
1
2
) = 0
     Multiply both sides of the equation by: x
     1 + 2 ÷ (1 + x ) × x + 1 ÷ ( x +
1
2
) × x = 0
     Multiply both sides of the equation by:(1 + x )
     1(1 + x ) + 2 x + 1 ÷ ( x +
1
2
) × x (1 + x ) = 0
    Remove a bracket on the left of the equation:
     1 × 1 + 1 x + 2 x + 1 ÷ ( x +
1
2
) × x (1 + x ) = 0
    The equation is reduced to :
     1 + 1 x + 2 x + 1 ÷ ( x +
1
2
) × x (1 + x ) = 0
    The equation is reduced to :
     1 + 3 x + 1 ÷ ( x +
1
2
) × x (1 + x ) = 0
     Multiply both sides of the equation by:( x +
1
2
)
     1( x +
1
2
) + 3 x ( x +
1
2
) + 1 x (1 + x ) = 0
    Remove a bracket on the left of the equation:
     1 x + 1 ×
1
2
+ 3 x ( x +
1
2
) + 1 x (1 + x ) = 0
    The equation is reduced to :
     1 x +
1
2
+ 3 x ( x +
1
2
) + 1 x (1 + x ) = 0
    Remove a bracket on the left of the equation:
     1 x +
1
2
+ 3 x x + 3 x ×
1
2
+ 1 x (1 + x ) = 0
    The equation is reduced to :
     1 x +
1
2
+ 3 x x +
3
2
x + 1 x (1 + x ) = 0
    The equation is reduced to :
     
5
2
x +
1
2
+ 3 x x + 1 x (1 + x ) = 0
    Remove a bracket on the left of the equation:
     
5
2
x +
1
2
+ 3 x x + 1 x × 1 + 1 x x = 0
    The equation is reduced to :
     
5
2
x +
1
2
+ 3 x x + 1 x + 1 x x = 0
    The equation is reduced to :
     
7
2

1
2
+ 3 x x + 1 x x = 0

    The solution of the equation:
        x1≈-0.695194 , keep 6 decimal places
        x2≈-0.179806 , keep 6 decimal places
    
    There are 2 solution(s).
