Answer 2

It seems like there might be some text or characters at the end of your inequality that don't make sense. However, I'll help you solve the inequality that you've provided:

-15 < 4x + 1 < 9

To solve this compound inequality, you'll want to isolate the variable x. Here's how you can do it step by step:

1. Start with the middle part of the inequality: 4x + 1 < 9

2. Subtract 1 from both sides: 4x < 9 - 1 4x < 8

3. Divide both sides by 4 to isolate x: x < 8 / 4 x < 2

Now, you've solved the middle part of the inequality. Let's move on to the left part:

-15 < 4x + 1

1. Subtract 1 from both sides: -15 - 1 < 4x -16 < 4x

2. Divide both sides by 4 to isolate x: -16 / 4 < 4x / 4 -4 < x

Now you have the left part of the inequality:

-4 < x

So, the solution to the compound inequality is:

-4 < x < 2

This means that x can be any value between -4 and 2, but not including -4 and 2 themselves.
