1. Problem Description

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

2. Solution Steps

First, we distribute the 34\frac{3}{4} in the term 34(x+2)\frac{3}{4}(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
Now, we can combine the constants on the left side:
4+32=82+32=1124 + \frac{3}{2} = \frac{8}{2} + \frac{3}{2} = \frac{11}{2}
So, the inequality becomes:
112+34x38x+1\frac{11}{2} + \frac{3}{4}x \le \frac{3}{8}x + 1
Next, we subtract 38x\frac{3}{8}x from both sides:
112+34x38x1\frac{11}{2} + \frac{3}{4}x - \frac{3}{8}x \le 1
To combine the x terms, we need a common denominator, which is 8:
34x=68x\frac{3}{4}x = \frac{6}{8}x
So, 68x38x=38x\frac{6}{8}x - \frac{3}{8}x = \frac{3}{8}x
112+38x1\frac{11}{2} + \frac{3}{8}x \le 1
Now, subtract 112\frac{11}{2} from both sides:
38x1112\frac{3}{8}x \le 1 - \frac{11}{2}
1112=22112=921 - \frac{11}{2} = \frac{2}{2} - \frac{11}{2} = -\frac{9}{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}
x9823x \le -\frac{9 \cdot 8}{2 \cdot 3}
x726x \le -\frac{72}{6}
x12x \le -12

3. Final Answer

x12x \le -12
