Answer 2

Solving the Double Inequality

To solve the double inequality -4 < 3x - 1 < 8, we need to find the values of x that satisfy both inequalities simultaneously.

First, let's solve the individual inequalities:

1. -4 < 3x - 1: - Add 1 to both sides: -3 < 3x - Divide by 3: -1 < x

2. 3x - 1 < 8: - Add 1 to both sides: 3x < 9 - Divide by 3: x < 3

So, the solution to the double inequality is -1 < x < 3.

Therefore, the values of x that satisfy the double inequality are all real numbers between -1 and 3, excluding -1 and 3.

I hope this helps! If you have any further questions, feel free to ask.
