[ 1/1 Equation]
    Work: Find the solution of equation 8/(3x-3)-(2+x)/(x-1)+5/(2-2x)-5/18 = 0 .
    Question type: Equation
    Solution:Original question:
     8 ÷ (3 x 3)(2 + x ) ÷ ( x 1) + 5 ÷ (22 x )5 ÷ 18 = 0
     Multiply both sides of the equation by:(3 x 3)
     8(2 + x ) ÷ ( x 1) × (3 x 3) + 5 ÷ (22 x ) × (3 x 3)5 ÷ 18 × (3 x 3) = 0
    Remove a bracket on the left of the equation::
     82 ÷ ( x 1) × (3 x 3) x ÷ ( x 1) × (3 x 3) + 5 ÷ (22 x ) × (3 x 3)5 ÷ 18 = 0
    The equation is reduced to :
     82 ÷ ( x 1) × (3 x 3) x ÷ ( x 1) × (3 x 3) + 5 ÷ (22 x ) × (3 x 3)
5
18
(3 x 3) = 0
     Multiply both sides of the equation by:( x 1)
     8( x 1)2(3 x 3) x (3 x 3) + 5 ÷ (22 x ) × (3 x 3)( x 1)
5
18
(3 x 3) = 0
    Remove a bracket on the left of the equation:
     8 x 8 × 12(3 x 3) x (3 x 3) + 5 ÷ (22 x ) × (3 x 3)( x 1) = 0
    The equation is reduced to :
     8 x 82(3 x 3) x (3 x 3) + 5 ÷ (22 x ) × (3 x 3)( x 1)
5
18
= 0
     Multiply both sides of the equation by:(22 x )
     8 x (22 x )8(22 x )2(3 x 3)(22 x ) x (3 x 3)(22 x ) + 5 = 0
    Remove a bracket on the left of the equation:
     8 x × 28 x × 2 x 8(22 x )2(3 x 3)(22 x ) = 0
    The equation is reduced to :
     16 x 16 x x 8(22 x )2(3 x 3)(22 x ) x (3 x 3) = 0
    Remove a bracket on the left of the equation:
     16 x 16 x x 8 × 2 + 8 × 2 x 2(3 x 3) = 0
    The equation is reduced to :
     16 x 16 x x 16 + 16 x 2(3 x 3)(22 x ) x = 0
    The equation is reduced to :
     32 x 16 x x 162(3 x 3)(22 x ) x (3 x 3)(22 x ) = 0
    Remove a bracket on the left of the equation:
     32 x 16 x x 162 × 3 x (22 x ) + 2 × 3 = 0
    The equation is reduced to :
     32 x 16 x x 166 x (22 x ) + 6(22 x ) x = 0
    Remove a bracket on the left of the equation:
     32 x 16 x x 166 x × 2 + 6 x × 2 = 0
    The equation is reduced to :
     32 x 16 x x 1612 x + 12 x x + 6 = 0
    The equation is reduced to :
     20 x 16 x x 16 + 12 x x + 6(22 x ) x = 0
    Remove a bracket on the left of the equation:
     20 x 16 x x 16 + 12 x x + 6 × 26 = 0
    The equation is reduced to :
     20 x 16 x x 16 + 12 x x + 1212 x = 0
    The equation is reduced to :
     8 x 16 x x 4 + 12 x x x (3 x 3)(22 x ) = 0
    Remove a bracket on the left of the equation:
     8 x 16 x x 4 + 12 x x x × 3 x = 0
    Remove a bracket on the left of the equation:
     8 x 16 x x 4 + 12 x x x × 3 x = 0

    the solutions is:
        x≈-1.217391 , keep 6 decimal places
    
    There are 1 solution(s).
