3|5t-1|+9<23
3|5t-1) less than 14
|5t-1| less than (14/3)
5t-1 less than 14/3
5t less than 15/3=5
t less than 1
;
5t-1 greater than -(14/3)
5t greater than -13/3
t greater than -13/15
;
Check with 2, which shouldn't work. 3|10-1|+9=36, and not less than 23.
Try 0, which should work. 3|-1|+9=12, and that is less than 23.
-3/2 should not work. 3|-.8.5| +9 =34.5 and that is not less than 23.
(-13/15,1)
