o If x < 3, then the inequation becomes:

<=> 7 < 3x
<x> 7/3

x-3<2x-4
<x> 1
=> x >= 3
Finally, we have : x > 7/3
Hi Fig,
Why have you mentioned that x >=3 and not that x > 3.. I see absolute Questions which sometimes have the >= sign and sometimes the > sign only.. Might be a very mindless question
but hope you would answer..
Not meaningless but rather precised question
...
Actually, it's just to avoid adding 1 solution alone from another interval... and so to meet a higher degree of "perfection" by making it a smoother way to the final solution and a straightforward simplicity to understand
Note that nothing is wrong if we say > or >= as soon as we do not miss to consider all values of x, especially here the ones that limit 2 intervals
