[ 1/1 Equation]
    Work: Find the solution of equation 2/x+1/(x+10) = 1/(x+1) .
    Question type: Equation
    Solution:Original question:
     2 ÷ x + 1 ÷ ( x + 10) = 1 ÷ ( x + 1)
     Multiply both sides of the equation by: x  ,  ( x + 1)
     2( x + 1) + 1 ÷ ( x + 10) × x ( x + 1) = 1 x
    Remove a bracket on the left of the equation::
     2 x + 2 × 1 + 1 ÷ ( x + 10) × x ( x + 1) = 1 x
    The equation is reduced to :
     2 x + 2 + 1 ÷ ( x + 10) × x ( x + 1) = 1 x
     Multiply both sides of the equation by:( x + 10)
     2 x ( x + 10) + 2( x + 10) + 1 x ( x + 1) = 1 x ( x + 10)
    Remove a bracket on the left of the equation:
     2 x x + 2 x × 10 + 2( x + 10) + 1 x ( x + 1) = 1 x ( x + 10)
    Remove a bracket on the right of the equation::
     2 x x + 2 x × 10 + 2( x + 10) + 1 x ( x + 1) = 1 x x + 1 x × 10
    The equation is reduced to :
     2 x x + 20 x + 2( x + 10) + 1 x ( x + 1) = 1 x x + 10 x
    Remove a bracket on the left of the equation:
     2 x x + 20 x + 2 x + 2 × 10 + 1 x ( x + 1) = 1 x x + 10 x
    The equation is reduced to :
     2 x x + 20 x + 2 x + 20 + 1 x ( x + 1) = 1 x x + 10 x
    The equation is reduced to :
     2 x x + 22 x + 20 + 1 x ( x + 1) = 1 x x + 10 x
    Remove a bracket on the left of the equation:
     2 x x + 22 x + 20 + 1 x x + 1 x × 1 = 1 x x + 10 x
    The equation is reduced to :
     2 x x + 22 x + 20 + 1 x x + 1 x = 1 x x + 10 x
    The equation is reduced to :
     2 x x + 23 x + 20 + 1 x x = 1 x x + 10 x

    After the equation is converted into a general formula, it is converted into:
    ( x + 4 )( 2x + 5 )=0
    From
        x + 4 = 0
        2x + 5 = 0

    it is concluded that::
        x1=-4
        x2=-
5
2
    
    There are 2 solution(s).
