Math Problem Statement

Solve the inequality: (- 3|6 - x| >= - 3) (2)

Solution

Let's solve the inequality step by step:

Given the inequality:

36x3-3|6 - x| \geq -3

Step 1: Divide both sides by -3

Since we are dividing by a negative number, the inequality's direction will change:

6x1|6 - x| \leq 1

Step 2: Solve the absolute value inequality

The inequality 6x1|6 - x| \leq 1 implies that:

16x1-1 \leq 6 - x \leq 1

Step 3: Solve for xx

Now, solve the compound inequality for xx:

  1. For the left part: 16x-1 \leq 6 - x Subtract 6 from both sides: 7x-7 \leq -x Multiply both sides by -1 (and reverse the inequality): 7xorx77 \geq x \quad \text{or} \quad x \leq 7

  2. For the right part: 6x16 - x \leq 1 Subtract 6 from both sides: x5-x \leq -5 Multiply both sides by -1 (and reverse the inequality): x5x \geq 5

Step 4: Combine the results

We now have the inequality:

5x75 \leq x \leq 7

Final Solution:

The solution to the inequality is:

x[5,7]x \in [5, 7]

This means that xx can take any value between 5 and 7, inclusive.
