1. Problem Description

The problem is to solve the absolute value inequality 2x17|2x - 1| \ge 7.

2. Solution Steps

To solve the absolute value inequality 2x17|2x - 1| \ge 7, we need to consider two cases:
Case 1: 2x172x - 1 \ge 7
Add 1 to both sides:
2x7+12x \ge 7 + 1
2x82x \ge 8
Divide both sides by 2:
x82x \ge \frac{8}{2}
x4x \ge 4
Case 2: 2x172x - 1 \le -7
Add 1 to both sides:
2x7+12x \le -7 + 1
2x62x \le -6
Divide both sides by 2:
x62x \le \frac{-6}{2}
x3x \le -3
Thus, the solution is x3x \le -3 or x4x \ge 4.

3. Final Answer

x3x \le -3 or x4x \ge 4
