[ 1/1 Equation]
    Work: Find the solution of equation 1/x+1/(x+50)+1/(x+250) = 1/(x+50) .
    Question type: Equation
    Solution:Original question:
     1 ÷ x + 1 ÷ ( x + 50) + 1 ÷ ( x + 250) = 1 ÷ ( x + 50)
     Multiply both sides of the equation by: x  ,  ( x + 50)
     1( x + 50) + 1 x + 1 ÷ ( x + 250) × x ( x + 50) = 1 x
    Remove a bracket on the left of the equation::
     1 x + 1 × 50 + 1 x + 1 ÷ ( x + 250) × x ( x + 50) = 1 x
    The equation is reduced to :
     1 x + 50 + 1 x + 1 ÷ ( x + 250) × x ( x + 50) = 1 x
    The equation is reduced to :
     2 x + 50 + 1 ÷ ( x + 250) × x ( x + 50) = 1 x
     Multiply both sides of the equation by:( x + 250)
     2 x ( x + 250) + 50( x + 250) + 1 x ( x + 50) = 1 x ( x + 250)
    Remove a bracket on the left of the equation:
     2 x x + 2 x × 250 + 50( x + 250) + 1 x ( x + 50) = 1 x ( x + 250)
    Remove a bracket on the right of the equation::
     2 x x + 2 x × 250 + 50( x + 250) + 1 x ( x + 50) = 1 x x + 1 x × 250
    The equation is reduced to :
     2 x x + 500 x + 50( x + 250) + 1 x ( x + 50) = 1 x x + 250 x
    Remove a bracket on the left of the equation:
     2 x x + 500 x + 50 x + 50 × 250 + 1 x ( x + 50) = 1 x x + 250 x
    The equation is reduced to :
     2 x x + 500 x + 50 x + 12500 + 1 x ( x + 50) = 1 x x + 250 x
    The equation is reduced to :
     2 x x + 550 x + 12500 + 1 x ( x + 50) = 1 x x + 250 x
    Remove a bracket on the left of the equation:
     2 x x + 550 x + 12500 + 1 x x + 1 x × 50 = 1 x x + 250 x
    The equation is reduced to :
     2 x x + 550 x + 12500 + 1 x x + 50 x = 1 x x + 250 x
    The equation is reduced to :
     2 x x + 600 x + 12500 + 1 x x = 1 x x + 250 x

    
        x1=-125
    
    There are 1 solution(s).
