[ 1/1 Equation]
    Work: Find the solution of equation 2/x+1/(x+9) = 1/(x+5) .
    Question type: Equation
    Solution:Original question:
     2 ÷ x + 1 ÷ ( x + 9) = 1 ÷ ( x + 5)
     Multiply both sides of the equation by: x  ,  ( x + 5)
     2( x + 5) + 1 ÷ ( x + 9) × x ( x + 5) = 1 x
    Remove a bracket on the left of the equation::
     2 x + 2 × 5 + 1 ÷ ( x + 9) × x ( x + 5) = 1 x
    The equation is reduced to :
     2 x + 10 + 1 ÷ ( x + 9) × x ( x + 5) = 1 x
     Multiply both sides of the equation by:( x + 9)
     2 x ( x + 9) + 10( x + 9) + 1 x ( x + 5) = 1 x ( x + 9)
    Remove a bracket on the left of the equation:
     2 x x + 2 x × 9 + 10( x + 9) + 1 x ( x + 5) = 1 x ( x + 9)
    Remove a bracket on the right of the equation::
     2 x x + 2 x × 9 + 10( x + 9) + 1 x ( x + 5) = 1 x x + 1 x × 9
    The equation is reduced to :
     2 x x + 18 x + 10( x + 9) + 1 x ( x + 5) = 1 x x + 9 x
    Remove a bracket on the left of the equation:
     2 x x + 18 x + 10 x + 10 × 9 + 1 x ( x + 5) = 1 x x + 9 x
    The equation is reduced to :
     2 x x + 18 x + 10 x + 90 + 1 x ( x + 5) = 1 x x + 9 x
    The equation is reduced to :
     2 x x + 28 x + 90 + 1 x ( x + 5) = 1 x x + 9 x
    Remove a bracket on the left of the equation:
     2 x x + 28 x + 90 + 1 x x + 1 x × 5 = 1 x x + 9 x
    The equation is reduced to :
     2 x x + 28 x + 90 + 1 x x + 5 x = 1 x x + 9 x
    The equation is reduced to :
     2 x x + 33 x + 90 + 1 x x = 1 x x + 9 x
    
    There are 0 solution(s).
