Math Problem Statement

|x + 5| ≤ 10

Solution

The inequality in the image reads:

x+510|x + 5| \leq 10

This is an absolute value inequality. To solve this inequality, we follow these steps:

Step 1: Remove the absolute value

For any inequality of the form AB|A| \leq B, we rewrite it as:

BAB- B \leq A \leq B

In this case:

10x+510-10 \leq x + 5 \leq 10

Step 2: Solve the inequality

Now, we solve for xx by isolating it in the middle part of the inequality.

  • Subtract 5 from all three parts:

105x105-10 - 5 \leq x \leq 10 - 5

15x5-15 \leq x \leq 5

Final Answer:

The solution to the inequality is:

15x5-15 \leq x \leq 5

Interval Notation:

The solution can be written in interval notation as:

x[15,5]x \in [-15, 5]

Tip: When solving absolute value inequalities, always remember to break them down into two cases: one for the positive side and one for the negative side!
