Step-by-step explanation:
2x−3<x+2≤3x+5
Let's break this up into two parts
First
2x−3<x+2 (add 3 to both sides)
2x<x+5 (subtract x from both sides)
x<5
Secondly
x+2≤3x+5
(subtract 5 from both sides)
x−3≤3x (subtract x from both sides)
−3<=2x divide both sides by 2)
−3≤2x (which also means x≥−

Thus

≤x<5
Or in interval notation

,5)
Try picking some values outside this interval. You'll find that they won't satisfy both inequalities
