[ 1/1 Equation]
    Work: Find the solution of equation 20+2000/x-90x-8000/[(x-1)x] = 0 .
    Question type: Equation
    Solution:Original question:
     20 + 2000 ÷ x 90 x 8000 ÷ (( x 1) x ) = 0
     Multiply both sides of the equation by: x
     20 x + 200090 x x 8000 ÷ (( x 1) × 1) × 1 = 0
     Multiply both sides of the equation by:(( x 1) × 1)
     20 x (( x 1) × 1) + 2000(( x 1) × 1)90 x x (( x 1) × 1)8000 × 1 = 0
    Remove a bracket on the left of the equation:
     20 x ( x 1) × 1 + 2000(( x 1) × 1)90 x x (( x 1) × 1)8000 × 1 = 0
    The equation is reduced to :
     20 x ( x 1) + 2000(( x 1) × 1)90 x x (( x 1) × 1)8000 = 0
    Remove a bracket on the left of the equation:
     20 x x 20 x × 1 + 2000(( x 1) × 1)90 x x (( x 1) × 1) = 0
    The equation is reduced to :
     20 x x 20 x + 2000(( x 1) × 1)90 x x (( x 1) × 1)8000 = 0
    Remove a bracket on the left of the equation:
     20 x x 20 x + 2000( x 1) × 190 x x (( x 1) × 1) = 0
    The equation is reduced to :
     20 x x 20 x + 2000( x 1)90 x x (( x 1) × 1)8000 = 0
    Remove a bracket on the left of the equation:
     20 x x 20 x + 2000 x 2000 × 190 x x = 0
    The equation is reduced to :
     20 x x 20 x + 2000 x 200090 x x (( x 1) × 1) = 0
    The equation is reduced to :
     20 x x + 1980 x 1000090 x x (( x 1) × 1) = 0
    Remove a bracket on the left of the equation:
     20 x x + 1980 x 1000090 x x ( x 1) × 1 = 0
    The equation is reduced to :
     20 x x + 1980 x 1000090 x x ( x 1) = 0
    Remove a bracket on the left of the equation:
     20 x x + 1980 x 1000090 x x x + 90 x = 0
    The equation is reduced to :
     20 x x + 1980 x 1000090 x x x + 90 x = 0

    
        x≈-5.826536 , keep 6 decimal places
    
    There are 1 solution(s).
