分式方程2-
|
答案
原方程化为
=2-x,1 4- 3 6- 5 2- 1 4- 3 6- 5 x
∴4-
=3 6- 5 2- 1 4- 3 6- 5 x
,即1 2-x
=3 6- 5 2- 1 4- 3 6- 5 x
,7-4x 2-x
6-
=5 2- 1 4- 3 6- 5 x
,即6-3x 7-4x
=5 2- 1 4- 3 6- 5 x
,36-21x 7-4x
∴2-
=1 4- 3 6- 5 x
,即35-20x 36-21x
=1 4- 3 6- 5 x
,37-22x 36-21x
∴4-
=3 6- 5 x
,即36-21x 37-22x
=3 6- 5 x
,112-67x 37-22x
∴6-
=5 x
,即111-66x 112-67x
=6-1+5 x
,1-x 112-67x
整理,得
-5(1-x) x
=0,1-x 112-67x
解得x1=1,x2=
.5 3
经检验:x1=1,x2=
是原方程的根.5 3
故答案为:x1=1,x2=
.5 3
