-3x + 1/4 > x - 5
-3x - x > -1/4 - 5
-4x > -1/4 - 20/4
-4x > -21/4
x < (-21/4)/-4
x < (-21/4)(-1/4)
x < 21/16
(the greatest integer: 1)
-3x - x > -1/4 - 5
-4x > -1/4 - 20/4
-4x > -21/4
x < (-21/4)/-4
x < (-21/4)(-1/4)
x < 21/16
(the greatest integer: 1)

- 3x + 1/4 > x - 5
20/4 + 1/4 > x + 3x
21/4 > 4x
21/16 > x
x < 21/16 or 1 5/16
Answer: x < 1 5/16
20/4 + 1/4 > x + 3x
21/4 > 4x
21/16 > x
x < 21/16 or 1 5/16
Answer: x < 1 5/16

hmm... hello~!
well,, inequalities aren't my thing.. but that's what I got..
I solved it this way::
-3x+1/4>x-5
-3x+0.25>x-5 ..... (I hate fractions so I made it into decimal)
-3x-x>-0.25-5 ..... (I changed the places of bot the (0.25) and the (x) so I've changed signs)
-4x>-5.25
x>-5.25/-4
x>1.3125
so x is greater than 1.3125
... I think i's true but I can't gurantee that.. hope it's true
gd luck
