Respuesta :

3/ x -1 - 4 / x + 2=2
I work a bit backwards so, lets try looking at it like this,
3/ X
 -4/X
what could X be to let these be positive since our outcome is positive? 
3/0=0
4/0=0
so 3/0-1= -1
-1-4/0= 0
+2= 2
so 2=2 
so now we go and fill it in to make sure
3/0-1-4/0+2=2
and it works so,
X= 0
I hope this helped some
