Question

0 < [ x -5 ] < 1/2

Answer 1

maybe it's just me... .but ... not sure I get it... what does it mean by [ x -5 ], is just a plain grouping or a floor() ?

Answer 2

your solving the inequality

Answer 3

so, it's just 0 < x-5 < 1/2 then?

Answer 4

yes

Answer 5

say if you had only x-5 < 1/2
how would you isolate "x"?

Answer 6

is really the same as solving an equation, the only difference is that in an equation, you have left-side and right-side, and anything you apply to one you apply to both

in this case, you have left-side, middle-side, right-side
and anything you do to one, you apply to all 3

so if you have to say ADD 5 to get rid of it in the middle
you add it to the ALL SIDES, to the left-side and right-side and middle side
