[ 1/1 Equation]
    Work: Find the solution of equation 1/x+2/(4+x)+1/(1+x)-1/(x+10) = 0 .
    Question type: Equation
    Solution:Original question:
     1 ÷ x + 2 ÷ (4 + x ) + 1 ÷ (1 + x )1 ÷ ( x + 10) = 0
     Multiply both sides of the equation by: x
     1 + 2 ÷ (4 + x ) × x + 1 ÷ (1 + x ) × x 1 ÷ ( x + 10) × x = 0
     Multiply both sides of the equation by:(4 + x )
     1(4 + x ) + 2 x + 1 ÷ (1 + x ) × x (4 + x )1 ÷ ( x + 10) × x (4 + x ) = 0
    Remove a bracket on the left of the equation:
     1 × 4 + 1 x + 2 x + 1 ÷ (1 + x ) × x (4 + x )1 ÷ ( x + 10) = 0
    The equation is reduced to :
     4 + 1 x + 2 x + 1 ÷ (1 + x ) × x (4 + x )1 ÷ ( x + 10) × x = 0
    The equation is reduced to :
     4 + 3 x + 1 ÷ (1 + x ) × x (4 + x )1 ÷ ( x + 10) × x (4 + x ) = 0
     Multiply both sides of the equation by:(1 + x )
     4(1 + x ) + 3 x (1 + x ) + 1 x (4 + x )1 ÷ ( x + 10) × x (4 + x ) = 0
    Remove a bracket on the left of the equation:
     4 × 1 + 4 x + 3 x (1 + x ) + 1 x (4 + x )1 ÷ ( x + 10) = 0
    The equation is reduced to :
     4 + 4 x + 3 x (1 + x ) + 1 x (4 + x )1 ÷ ( x + 10) × x = 0
     Multiply both sides of the equation by:( x + 10)
     4( x + 10) + 4 x ( x + 10) + 3 x (1 + x )( x + 10) + 1 x (4 + x ) = 0
    Remove a bracket on the left of the equation:
     4 x + 4 × 10 + 4 x ( x + 10) + 3 x (1 + x )( x + 10) + 1 = 0
    The equation is reduced to :
     4 x + 40 + 4 x ( x + 10) + 3 x (1 + x )( x + 10) + 1 x = 0
    Remove a bracket on the left of the equation:
     4 x + 40 + 4 x x + 4 x × 10 + 3 x (1 + x ) = 0
    The equation is reduced to :
     4 x + 40 + 4 x x + 40 x + 3 x (1 + x )( x + 10) = 0
    The equation is reduced to :
     44 x + 40 + 4 x x + 3 x (1 + x )( x + 10) + 1 x = 0
    Remove a bracket on the left of the equation:
     44 x + 40 + 4 x x + 3 x × 1( x + 10) + 3 x = 0
    The equation is reduced to :
     44 x + 40 + 4 x x + 3 x ( x + 10) + 3 x x = 0
    Remove a bracket on the left of the equation:
     44 x + 40 + 4 x x + 3 x x + 3 x × 10 = 0
    The equation is reduced to :
     44 x + 40 + 4 x x + 3 x x + 30 x + 3 = 0
    The equation is reduced to :
     74 x + 40 + 4 x x + 3 x x + 3 x x = 0
    Remove a bracket on the left of the equation:
     74 x + 40 + 4 x x + 3 x x + 3 x x = 0
    The equation is reduced to :
     74 x + 40 + 4 x x + 3 x x + 3 x x = 0

    The solution of the equation:
        x1≈-12.481164 , keep 6 decimal places
        x2≈-2.408653 , keep 6 decimal places
        x3≈-0.443516 , keep 6 decimal places
    
    There are 3 solution(s).
