Question 54266: To solve for this equation,  or  I would have to do the same to both sides correct? if I (-5) to the 11 side I must do the same to the 8 side right? From there I would solve for x normally and that gives me the 2 answers? I think I have the logic down, just need to make sure my steps are correct.
Thank you

Question 54300: Absolute value of(2x+5) is less than or equal to 3.
/2x+5/<=3
I set it up according to the rule /ax+b/<=c then -c<=ax-b<=c
so
-3<=2x+5<=3
-5 -5 -5
-8<=2x<=-2
-4<=x<=-1
Interval notation would be [-4,-1]
However, my teacher's answer sheet to the review problem shows -4
or in interval notation (-4,-1]
why would -4 be less than and not less than or equal to x?
