解分式方程:3-x/x-2-1=5/2-x解分式方程:3-x/x-2-1=5/2-x解分式方程:3-x/x-2-1=5/2-x(3-x)/(x-2)-1=5/(2-x)==>(3-x)/(x-2)-5

解分式方程:3-x/x-2-1=5/2-x
解分式方程:3-x/x-2-1=5/2-x

解分式方程:3-x/x-2-1=5/2-x
(3-x)/(x-2) -1 = 5/(2-x) ==> (3-x)/(x-2) - 5/(2 - x) = 1 ==> (3-x)/(x - 2) + 5/(x - 2) = 1 ==> (3-x + 5)/(x-2) = 1 ==> (8-x) / (x - 2) = 1 ==> 8-x = x - 2 ==> 2x = 10 ==> x = 5
