[ 1/1 Equation]
    Work: Find the solution of equation 1/d+1/(d+25)+1/(d+100) = 1/(d+38) .
    Question type: Equation
    Solution:Original question:
     1 ÷ d + 1 ÷ ( d + 25) + 1 ÷ ( d + 100) = 1 ÷ ( d + 38)
     Multiply both sides of the equation by: d  ,  ( d + 38)
     1( d + 38) + 1 ÷ ( d + 25) × d ( d + 38) + 1 ÷ ( d + 100) × d ( d + 38) = 1 d
    Remove a bracket on the left of the equation::
     1 d + 1 × 38 + 1 ÷ ( d + 25) × d ( d + 38) + 1 ÷ ( d + 100) × d ( d + 38) = 1 d
    The equation is reduced to :
     1 d + 38 + 1 ÷ ( d + 25) × d ( d + 38) + 1 ÷ ( d + 100) × d ( d + 38) = 1 d
     Multiply both sides of the equation by:( d + 25)
     1 d ( d + 25) + 38( d + 25) + 1 d ( d + 38) + 1 ÷ ( d + 100) × d ( d + 38) = 1 d ( d + 25)
    Remove a bracket on the left of the equation:
     1 d d + 1 d × 25 + 38( d + 25) + 1 d ( d + 38) + 1 = 1 d ( d + 25)
    Remove a bracket on the right of the equation::
     1 d d + 1 d × 25 + 38( d + 25) + 1 d ( d + 38) + 1 = 1 d d + 1 d × 25
    The equation is reduced to :
     1 d d + 25 d + 38( d + 25) + 1 d ( d + 38) + 1 ÷ ( d + 100) = 1 d d + 25 d
     Multiply both sides of the equation by:( d + 100)
     1 d d ( d + 100) + 25 d ( d + 100) + 38( d + 25)( d + 100) + 1 d = 1 d d ( d + 100) + 25 d ( d + 100)
    Remove a bracket on the left of the equation:
     1 d d d + 1 d d × 100 + 25 d ( d + 100) + 38 = 1 d d ( d + 100) + 25 d ( d + 100)
    Remove a bracket on the right of the equation::
     1 d d d + 1 d d × 100 + 25 d ( d + 100) + 38 = 1 d d d + 1 d d × 100 + 25 d ( d + 100)
    The equation is reduced to :
     1 d d d + 100 d d + 25 d ( d + 100) + 38( d + 25) = 1 d d d + 100 d d + 25 d ( d + 100)
    Remove a bracket on the left of the equation:
     1 d d d + 100 d d + 25 d d + 25 d = 1 d d d + 100 d d + 25 d ( d + 100)
    Remove a bracket on the right of the equation::
     1 d d d + 100 d d + 25 d d + 25 d = 1 d d d + 100 d d + 25 d d + 25 d
    The equation is reduced to :
     1 d d d + 100 d d + 25 d d + 2500 d = 1 d d d + 100 d d + 25 d d + 2500 d
    Remove a bracket on the left of the equation:
     1 d d d + 100 d d + 25 d d + 2500 d = 1 d d d + 100 d d + 25 d d + 2500 d
    The equation is reduced to :
     1 d d d + 100 d d + 25 d d + 2500 d = 1 d d d + 100 d d + 25 d d + 2500 d
    Remove a bracket on the left of the equation:
     1 d d d + 100 d d + 25 d d + 2500 d = 1 d d d + 100 d d + 25 d d + 2500 d
    The equation is reduced to :
     1 d d d + 100 d d + 25 d d + 2500 d = 1 d d d + 100 d d + 25 d d + 2500 d
    The equation is reduced to :
     1 d d d + 100 d d + 25 d d + 6300 d = 1 d d d + 100 d d + 25 d d + 2500 d
    Remove a bracket on the left of the equation:
     1 d d d + 100 d d + 25 d d + 6300 d = 1 d d d + 100 d d + 25 d d + 2500 d
    The equation is reduced to :
     1 d d d + 100 d d + 25 d d + 6300 d = 1 d d d + 100 d d + 25 d d + 2500 d

    
        d≈-14.871593 , keep 6 decimal places
    
    There are 1 solution(s).
