2- 5*l 2x-3 l <
7
First we will need to isolate the absolute values on the
left side.
Let us subtract 2 from both
sides.
==> -5*l2x-3l <
5
Now we will divide by -5 and reverse the
inequality.
==> l 2x-3 l >
-1
==> 2x-3 >
-1
==> 2x >
2
=> x >
1...............(1)
-(2x-3) >
-1
==> 2x-3 <
1
==> 2x <
4
==> x <
2...............(2)
Now we will
rewrite:
==> -1 < 2x-3 <
1
Add 3 to all
sides.
==> 2 < 2x <
4
Now we will divide by
2.
==> 1 < x <
2
Then the values of x belongs to the
interval (1, 2)
