Math Problem Statement

Solve the following inequality algebraically: 5|5 - x| + 4 < 44

Solution

To solve the inequality:

55x+4<445|5 - x| + 4 < 44

Step 1: Isolate the absolute value term. First, subtract 4 from both sides:

55x<405|5 - x| < 40

Step 2: Divide by 5. Divide both sides of the inequality by 5 to simplify:

5x<8|5 - x| < 8

Step 3: Solve the absolute value inequality. The general rule for solving an inequality of the form A<B|A| < B is:

B<A<B-B < A < B

In this case:

8<5x<8-8 < 5 - x < 8

Step 4: Solve for xx. Now, solve the inequality by first subtracting 5 from all parts:

85<x<85-8 - 5 < -x < 8 - 5

13<x<3-13 < -x < 3

Finally, multiply through by 1-1 (which reverses the inequality signs):

13>x>313 > x > -3

This simplifies to:

3<x<13-3 < x < 13

Solution: The solution to the inequality is:

(3,13)(-3, 13)
