Answer:

-3 < x < 1

Explanation:

To solve the inequality 3|x+1| < 6, we need to isolate the absolute value expression and solve for the variable x. We can start by dividing both sides of the inequality by 3:

|x+1| < 2

Next, we can split the inequality into two separate cases, one for when x+1 is positive and one for when x+1 is negative. When x+1 is positive, we can remove the absolute value bars, so we have:

x+1 < 2

Solving for x, we get:

x < 1

When x+1 is negative, we need to distribute the negative sign that comes with the absolute value expression, so we have:

-(x+1) < 2

Multiplying both sides by -1 (which reverses the direction of the inequality), we have:

x+1 > -2

Subtracting 1 from both sides, we get:

x > -3

So the solution to the inequality is:

-3 < x < 1
