1. Problem Description

We need to solve the following inequality for xx:
9(2x3)4(2x3)-9(-2x - 3) \ge 4(2x - 3)

2. Solution Steps

First, distribute the constants on both sides of the inequality:
(9)(2x)+(9)(3)(4)(2x)+(4)(3)(-9)(-2x) + (-9)(-3) \ge (4)(2x) + (4)(-3)
18x+278x1218x + 27 \ge 8x - 12
Next, subtract 8x8x from both sides:
18x8x+278x8x1218x - 8x + 27 \ge 8x - 8x - 12
10x+271210x + 27 \ge -12
Subtract 27 from both sides:
10x+2727122710x + 27 - 27 \ge -12 - 27
10x3910x \ge -39
Divide both sides by 10:
10x103910\frac{10x}{10} \ge \frac{-39}{10}
x3910x \ge -\frac{39}{10}

3. Final Answer

x3910x \ge -\frac{39}{10}
