[ 1/1 Equation]
    Work: Find the solution of equation [2x/(x-2)]+1 = 5/(2-x) .
    Question type: Equation
    Solution:Original question:
     (2 x ÷ ( x − 2)) + 1 = 5 ÷ (2 − x )
     Multiply both sides of the equation by:(2 − x )
     (2 x ÷ ( x − 2))(2 − x ) + 1(2 − x ) = 5
    Remove a bracket on the left of the equation::
     2 x ÷ ( x − 2) × (2 − x ) + 1(2 − x ) = 5
     Multiply both sides of the equation by:( x − 2)
     2 x (2 − x ) + 1(2 − x )( x − 2) = 5( x − 2)
    Remove a bracket on the left of the equation:
     2 x × 2 − 2 x x + 1(2 − x )( x − 2) = 5( x − 2)
    Remove a bracket on the right of the equation::
     2 x × 2 − 2 x x + 1(2 − x )( x − 2) = 5 x − 5 × 2
    The equation is reduced to :
     4 x − 2 x x + 1(2 − x )( x − 2) = 5 x − 10
    Remove a bracket on the left of the equation:
     4 x − 2 x x + 1 × 2( x − 2) − 1 x ( x − 2) = 5 x − 10
    The equation is reduced to :
     4 x − 2 x x + 2( x − 2) − 1 x ( x − 2) = 5 x − 10
    Remove a bracket on the left of the equation:
     4 x − 2 x x + 2 x − 2 × 2 − 1 x ( x − 2) = 5 x − 10
    The equation is reduced to :
     4 x − 2 x x + 2 x − 4 − 1 x ( x − 2) = 5 x − 10
    The equation is reduced to :
     6 x − 2 x x − 4 − 1 x ( x − 2) = 5 x − 10
    Remove a bracket on the left of the equation:
     6 x − 2 x x − 4 − 1 x x + 1 x × 2 = 5 x − 10
    The equation is reduced to :
     6 x − 2 x x − 4 − 1 x x + 2 x = 5 x − 10
    The equation is reduced to :
     8 x − 2 x x − 4 − 1 x x = 5 x − 10

    the solutions is:
        x1=-1
    
    There are 1 solution(s).
