Studdy Solution

STEP 1

Assumptions
1. We are solving the inequality $3|x+1|-2<4$ .
2. We will consider two cases for the absolute value: when $x+1 \geq 0$ and when $x+1 < 0$ .

STEP 2

First, we isolate the absolute value term by adding 2 to both sides of the inequality.
$3|x+1|-2+2<4+2$

STEP 3

Simplify the inequality.
$3|x+1|<6$

STEP 4

Next, we divide both sides of the inequality by 3 to isolate the absolute value.
$\frac{3|x+1|}{3}<\frac{6}{3}$

STEP 5

Simplify the inequality.
$|x+1|<2$

STEP 6

Now we consider the two cases for the absolute value:
Case 1: $x+1 \geq 0$
Case 2: $x+1 < 0$

STEP 7

For Case 1, where $x+1 \geq 0$ , the absolute value can be removed without changing the sign.
$x+1<2$

STEP 8

Subtract 1 from both sides of the inequality to solve for $x$ in Case 1.
$x+1-1<2-1$

STEP 9

Simplify the inequality for Case 1.
$x<1$

STEP 10

For Case 2, where $x+1 < 0$ , the absolute value will change the sign of the expression inside it.
$-(x+1)<2$

STEP 11

Distribute the negative sign inside the parentheses.
$-x-1<2$

STEP 12

Add 1 to both sides of the inequality to solve for $x$ in Case 2.
$-x-1+1<2+1$

STEP 13

Simplify the inequality for Case 2.
$-x<3$

STEP 14

Multiply both sides of the inequality by -1 to solve for $x$ in Case 2. Remember that multiplying or dividing by a negative number reverses the inequality sign.
$-1(-x)>-1(3)$

STEP 15

Simplify the inequality for Case 2.
$x>-3$

STEP 16

Combine the results from Case 1 and Case 2. The solution to the inequality is the union of the two cases.
$-3<x<1$

STEP 17

The solution to the inequality $3|x+1|-2<4$ is $-3<x<1$ , which corresponds to option C.
C) $-3<x<1$
