1. Problem Description

The problem is to solve the inequality 323x173 - 2|3x - 1| \ge -7.

2. Solution Steps

First, we isolate the absolute value term.
Subtract 3 from both sides of the inequality:
323x13733 - 2|3x - 1| - 3 \ge -7 - 3
23x110-2|3x - 1| \ge -10
Next, divide both sides by -

2. Remember that dividing by a negative number reverses the inequality sign:

23x12102\frac{-2|3x - 1|}{-2} \le \frac{-10}{-2}
3x15|3x - 1| \le 5
Now we consider the definition of absolute value, which implies that
53x15-5 \le 3x - 1 \le 5
We solve this compound inequality by adding 1 to all parts:
5+13x1+15+1-5 + 1 \le 3x - 1 + 1 \le 5 + 1
43x6-4 \le 3x \le 6
Finally, divide all parts by 3:
433x363\frac{-4}{3} \le \frac{3x}{3} \le \frac{6}{3}
43x2-\frac{4}{3} \le x \le 2

3. Final Answer

The solution to the inequality is 43x2-\frac{4}{3} \le x \le 2.
