[ 1/1 Equation]
    Work: Find the solution of equation 5/(x-1)+(3-x)/(1-x) = 2 .
    Question type: Equation
    Solution:Original question:
     5 ÷ ( x 1) + (3 x ) ÷ (1 x ) = 2
     Multiply both sides of the equation by:( x 1)
     5 + (3 x ) ÷ (1 x ) × ( x 1) = 2( x 1)
    Remove a bracket on the left of the equation::
     5 + 3 ÷ (1 x ) × ( x 1) x ÷ (1 x ) × ( x 1) = 2( x 1)
    Remove a bracket on the right of the equation::
     5 + 3 ÷ (1 x ) × ( x 1) x ÷ (1 x ) × ( x 1) = 2 x 2 × 1
    The equation is reduced to :
     5 + 3 ÷ (1 x ) × ( x 1) x ÷ (1 x ) × ( x 1) = 2 x 2
     Multiply both sides of the equation by:(1 x )
     5(1 x ) + 3( x 1) x ( x 1) = 2 x (1 x )2(1 x )
    Remove a bracket on the left of the equation:
     5 × 15 x + 3( x 1) x ( x 1) = 2 x (1 x )2(1 x )
    Remove a bracket on the right of the equation::
     5 × 15 x + 3( x 1) x ( x 1) = 2 x × 12 x x 2(1 x )
    The equation is reduced to :
     55 x + 3( x 1) x ( x 1) = 2 x 2 x x 2(1 x )
    Remove a bracket on the left of the equation:
     55 x + 3 x 3 × 1 x ( x 1) = 2 x 2 x x 2(1 x )
    Remove a bracket on the right of the equation::
     55 x + 3 x 3 × 1 x ( x 1) = 2 x 2 x x 2 × 1 + 2 x
    The equation is reduced to :
     55 x + 3 x 3 x ( x 1) = 2 x 2 x x 2 + 2 x
    The equation is reduced to :
     22 x x ( x 1) = 4 x 2 x x 2
    Remove a bracket on the left of the equation:
     22 x x x + x × 1 = 4 x 2 x x 2
    The equation is reduced to :
     21 x x x = 4 x 2 x x 2

    
        x1=4
    
    There are 1 solution(s).
