Solve the absolute value:
| x + 1| + 3 <4

x<0 and x>-2

Step-by-step explanation:

x<0 and x>−2

Step-by-step explanation:

Step 1: Add -3 to both sides.

|x+1|+3+−3<4+−3

|x+1|<1

Step 2: Solve Absolute Value.

|x+1|<1

We know x+1<1 and x+1>−1

x+1<1(Condition 1)

x+1−1<1−1(Subtract 1 from both sides)

x<0

x+1>−1(Condition 2)

x+1−1>−1−1(Subtract 1 from both sides)

x>−2
