1. Problem Description

Solve the inequality 4x+72x14x + 7 \ge 2x - 1.

2. Solution Steps

We want to isolate xx on one side of the inequality.
First, subtract 2x2x from both sides:
4x+72x2x12x4x + 7 - 2x \ge 2x - 1 - 2x
2x+712x + 7 \ge -1
Next, subtract 77 from both sides:
2x+77172x + 7 - 7 \ge -1 - 7
2x82x \ge -8
Finally, divide both sides by 22:
2x282\frac{2x}{2} \ge \frac{-8}{2}
x4x \ge -4

3. Final Answer

x4x \ge -4
