[ 1/1 Equation]
    Work: Find the solution of equation 1/x+1/(10+x)+1/(25+x) = 0 .
    Question type: Equation
    Solution:Original question:
     1 ÷ x + 1 ÷ (10 + x ) + 1 ÷ (25 + x ) = 0
     Multiply both sides of the equation by: x
     1 + 1 ÷ (10 + x ) × x + 1 ÷ (25 + x ) × x = 0
     Multiply both sides of the equation by:(10 + x )
     1(10 + x ) + 1 x + 1 ÷ (25 + x ) × x (10 + x ) = 0
    Remove a bracket on the left of the equation:
     1 × 10 + 1 x + 1 x + 1 ÷ (25 + x ) × x (10 + x ) = 0
    The equation is reduced to :
     10 + 1 x + 1 x + 1 ÷ (25 + x ) × x (10 + x ) = 0
    The equation is reduced to :
     10 + 2 x + 1 ÷ (25 + x ) × x (10 + x ) = 0
     Multiply both sides of the equation by:(25 + x )
     10(25 + x ) + 2 x (25 + x ) + 1 x (10 + x ) = 0
    Remove a bracket on the left of the equation:
     10 × 25 + 10 x + 2 x (25 + x ) + 1 x (10 + x ) = 0
    The equation is reduced to :
     250 + 10 x + 2 x (25 + x ) + 1 x (10 + x ) = 0
    Remove a bracket on the left of the equation:
     250 + 10 x + 2 x × 25 + 2 x x + 1 x (10 + x ) = 0
    The equation is reduced to :
     250 + 10 x + 50 x + 2 x x + 1 x (10 + x ) = 0
    The equation is reduced to :
     250 + 60 x + 2 x x + 1 x (10 + x ) = 0
    Remove a bracket on the left of the equation:
     250 + 60 x + 2 x x + 1 x × 10 + 1 x x = 0
    The equation is reduced to :
     250 + 60 x + 2 x x + 10 x + 1 x x = 0
    The equation is reduced to :
     250 + 70 x + 2 x x + 1 x x = 0

    The solution of the equation:
        x1≈-18.931498 , keep 6 decimal places
        x2≈-4.401835 , keep 6 decimal places
    
    There are 2 solution(s).
