1. Problem Description

Solve the inequality 2+35x4-2 + 3|5 - x| \le 4.

2. Solution Steps

First, isolate the absolute value term by adding 2 to both sides of the inequality:
2+35x+24+2-2 + 3|5 - x| + 2 \le 4 + 2
35x63|5 - x| \le 6
Next, divide both sides by 3:
35x363\frac{3|5 - x|}{3} \le \frac{6}{3}
5x2|5 - x| \le 2
Now, we can rewrite the absolute value inequality as a compound inequality:
25x2-2 \le 5 - x \le 2
We can split this into two separate inequalities:
5x25 - x \le 2 and 5x25 - x \ge -2
Solve the first inequality:
5x25 - x \le 2
x25-x \le 2 - 5
x3-x \le -3
x3x \ge 3
Solve the second inequality:
5x25 - x \ge -2
x25-x \ge -2 - 5
x7-x \ge -7
x7x \le 7
Combining these two inequalities, we have:
3x73 \le x \le 7

3. Final Answer

3x73 \le x \le 7
