Answer:
-2<x<=5.5
Step-by-step explanation:
-7<4x+1<=23
First taking 1st and 2nd part;
-7<4x+1
-7-1<4×+1-1 (subtracting -1 from both the sides)
-8<4x
-8/4<4x/4 (dividing by 4 on both the sides)
-2<x
Now taking the 2nd and the 3rd part;
4x+1<=23
4x+1-1<=23-1
4x<=22
4x/4<=22/4
x<=11/2 or x<=5.5
So..
-2<x<=5.5
