1. Problem Description

The problem is to solve the inequality 4+34(x+2)38x+14 + \frac{3}{4}(x+2) \le \frac{3}{8}x + 1.

2. Solution Steps

We start by distributing 34\frac{3}{4} to (x+2)(x+2).
4+34x+34(2)38x+14 + \frac{3}{4}x + \frac{3}{4}(2) \le \frac{3}{8}x + 1
4+34x+6438x+14 + \frac{3}{4}x + \frac{6}{4} \le \frac{3}{8}x + 1
4+34x+3238x+14 + \frac{3}{4}x + \frac{3}{2} \le \frac{3}{8}x + 1
Combine the constant terms on the left side.
82+32+34x38x+1\frac{8}{2} + \frac{3}{2} + \frac{3}{4}x \le \frac{3}{8}x + 1
112+34x38x+1\frac{11}{2} + \frac{3}{4}x \le \frac{3}{8}x + 1
Subtract 38x\frac{3}{8}x from both sides.
112+34x38x1\frac{11}{2} + \frac{3}{4}x - \frac{3}{8}x \le 1
112+68x38x1\frac{11}{2} + \frac{6}{8}x - \frac{3}{8}x \le 1
112+38x1\frac{11}{2} + \frac{3}{8}x \le 1
Subtract 112\frac{11}{2} from both sides.
38x1112\frac{3}{8}x \le 1 - \frac{11}{2}
38x22112\frac{3}{8}x \le \frac{2}{2} - \frac{11}{2}
38x92\frac{3}{8}x \le -\frac{9}{2}
Multiply both sides by 83\frac{8}{3}.
x9283x \le -\frac{9}{2} \cdot \frac{8}{3}
x726x \le -\frac{72}{6}
x12x \le -12

3. Final Answer

x12x \le -12
