```        Q1. How many roots does this equation possess?

3|x|-|2-|x||=1```

```										hi , rewrite the eq. as
3|x|-1 = |2-|x||
or, we can write
3|x|-1 =  ||x|-2|
we will now do the graphical analysis of both the function  3|x|-1   &  ||x|-2| .
if the graphs will intersect at apoint then at this point both the function will be equal
& this point will be the solu. of our eq.

we can  clearly say that there are only two solu. of the given eq.
to draw the graph of first one,
1 . first we draw the 3^x . changing its -x axis by +xaxis we will get 3|x| . by pulling it downward  at a unit distance we will make graph of 3|x| -1
for second function,
2.  draw the |x|  & pull it by 2 unit down ward . then we will invert that part of graph which is below x - axis  . this will be the graph of    ||x|-2|.
